This cutting-edge power quality instrument is designed with a color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can monitor, record and display data on four voltage channels and four current channels simultaneously. PX5 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for accuracy and measurement requirements. It can do PQ-optimized acquisition of power quality related disturbances and events. It is designed with a statistical package called Quality of Supply (QOS), with monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. European standard EN50160 requires that measurement parameters must be within a specified percentage for 95% of the time. PowerXplorer PX5 is available in two models: • Model PX5-XFAST is equipped with the high speed sampling analog board for microsecond transient detection digitization and analysis. The PX5-XFAST performs measurements for 50/60 Hz power frequency systems. • Model PX5-400 performs measurements for 400 Hz power frequency systems. The PX5-400 will also monitor at 50/60 Hz. The user needs to set the default frequency to either 400 Hz, 60 Hz or 50 Hz, depending on the application. When operating at 400 Hz, rms calculations are made on a cycle-by-cycle basis with 1 cycle step; whereas at 50/60 Hz mode, it steps at 1/2 Hz. Also, the PX5-400 does not calculate the IEEE 1459 power parameters as well as flicker, which are not defined at 400 Hz. The firmware for the PX5 is contained on internal FLASH memory. It has an operating PX5 Firmware system capable of performing multiple applications. When an updated version of the firmware is released, the user can upgrade the internal program by putting the latest PX5 firmware program card in the appropriate slot of the mainframe. See page 1-10 for instructions on how to upgrade PX5 firmware from a data card. The PX5 firmware can monitor power quality phenomena for troubleshooting and/or compliance purposes. It can record inrush conditions, carry out long-term statistical studies to establish performance baselines, and perform field-based equipment testing and evaluation for commissioning and maintenance. The firmware integrates an intuitive instrument setup procedure to ensure the capture of all relevant data for additional post process analysis, report writing, and data archiving using other compatible Dranetz-BMI software applications such as NodeLink® and DranView®. 1-1 Overview, continued This manual contains instructions for operating both PX5 models - PX5-XFAST and This manual PX5-400.

Users may use a finger and/or a PDA stylus to apply pressure to the LCD screen to result in touch screen recognition. The touch screen display is also workable with lineman gloves on. Touch screen buttons will appear in reverse-video to show visual feedback of contact along with audible feedback. In order to reduce power consumption, the backlight of the LCD screen times-out after a specified programmable time of no user activity. The backlight reactivates by touching any part of the screen. Scope mode functions as an oscilloscope, displaying real-time waveforms of voltage Scope mode and current for up to eight channels simultaneously, with one second update rate. The colors of waveform display are user programmable. Scope mode also provides a textual display of rms values, division for axis values, and frequency. Meter mode functions as a true rms voltmeter and a true rms clamp-on ammeter. Meter mode Voltage and current measurements, along with other calculated and advanced power parameters, are displayed on the Meter mode screens in both textual and graphical format. Harmonics display the amplitude and phase of each harmonic to the 63rd harmonic in Harmonics both graphical and textual format. The phasor screen displays a graph that indicates phase relations between voltage and Phasor diagram current based upon the angles at the fundamental frequency, as determined by Fourier analysis. Phasor diagram displays voltage and current phasors for all channels. Functioning as a phase angle meter, the unit can display system imbalance conditions and provides such information in textual form also. The phase angle display can also verify if monitoring connections have been made correctly. Animated phasor demo rotations demonstrating resistive, inductive and capacitive loads can be displayed. Flicker is a phenomenon due primarily to rapid small fluctuations of the voltage. Loads Flicker that exhibit continuous, rapid variations in the load current, particularly the reactive component, can cause voltage variations often referred to as flicker. Flicker is characterized by modulation at a frequency typically less than 25 Hz. Modulating signal magnitudes as low as 0.5% of the fundamental for frequencies between 5-10 Hz can result in perceptible light flicker. An event occurs when a programmed threshold limit is crossed. An event consists of Event the pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s). Continued on next page 1-12 CH 1/ Getting Started PX5 can monitor the following power configurations: Monitoring capacity • Single Phase • 3 Phase 2-Watt Meter Delta • Split Phase • Generic • 3 Phase Delta • 2 1/2 Element without VB • 3 Phase Wye • 2 1/2 Element without VC While monitoring any of the above configurations, the PX5 can also be connected to monitor neutral to ground voltage and neutral or ground current. Setup is a configuration of parameter thresholds that control the data recorded by PX5. Automatic setup, Wizard Users may perform instrument setup in three ways: via Automatic Setup which utilizes setup, or auto-configured settings and allows users to proceed directly with data monitoring; via Advanced setup Wizard Setup which follows a step-by-step sequence where users go through a series of circuit setup screens; or via Advanced Options setup which allows users to modify trigger parameters and intervals or tweak threshold settings. Trend Users can generate plots for all journalled data combined with min/max recordings of that parameter. Most journal parameters have multiple channels to plot. Users have two options on how to view QOS compliance reports. Reports EN50160 displays statistical reports on QOS compliance based on an analysis of the voltage as per requirements of the EN50160 standard. Compliance data is presented in bar charts, statistical tables, and graphs. Statistical data is calculated on the required parameters specified in EN50160 over one week interval to produce a PASS/FAIL decision of QOS compliance. Status presents a report summary for Standard PQ, EN50160, and Motor Quality parameters via the annunciator panel. The panel is color coded such that green indicates the parameter is within limits and/or no events have occurred since the last time the panel was cleared. Red indicates the parameter is out of limits and/or events of that type have occurred since last cleared. Unlike the EN50160 which reports on QOS compliance on a weekly basis, Status monitors compliance continuously. There is also the option to view a parameter in more detail i.e. display its data plot, threshold values, or edit parameter/channel settings. PX5 supports the use of Compact Flash data cards with AT LEAST 32MB storage Data Card capacity. The user replaceable data card serves as primary storage for data. Data monitoring CANNOT proceed without the data card. PX5 is designed to accommodate the Compact Flash card in its native format, and does not require the use of a PC card adapter. However, a PC card adapter can be used to read the data into a laptop or other computer with a PC card slot. 1-13 Basic Operation Basic Operation The normal power source for the PX5 is its internal battery pack.

The IEC 61000-4-7 Standard dictates that harmonic analysis is done using a synchronous window of 10 cycles for 50 Hz, or 12 cycles for 60 Hz. This results in bins which are nominally 5 Hz wide. The actual width of the bins is equal to the actual frequency divided by 10 if the nominal frequency is 50 Hz, and 12 if 60 Hz. For example, if actually operating at 49.9 Hz, the bin is 4.99 Hz, but is labelled “5 Hz” as specified by the standard. Use the respective touch screen buttons to display the next Channel (Channels A, B, C, D) and the next Parameter (V, I, W) of harmonic data. The number of harmonics/ interharmonics displayed is up to the 60th. Summary values of odd, even and total distortion are displayed. A summary of harmonic distortion as well as interharmonic distortion values per phase/parameter are also available on display. Users can determine the number or range of harmonic frequencies to trend and view in detail. There is also the option to select how to plot harmonic/interharmonic data and specify the units of measure by which harmonic data is calculated. Harmonic Graph: Harmonics are measured in accordance with IEC 61000-4-7 Class 1. Users can choose the unit of measure by which harmonic data is calculated and graphed, based on a Percentage of the fundamental value or in Engineering units (volts and amps). Frequency components of harmonic graphs can be displayed either in Hertz or in Harmonic Number. The graphs can be zoomed and rescaled. Harmonic List: The list gives a textual display of the following for each of the measured values: frequency and harmonic number; magnitude in Engineering units and percent of fundamental; phase in degrees (for harmonics only). This list is displayed in order of ascending frequency, and can also be sorted in order of descending magnitude. The following topics are covered in this section. In this section Topic See Page Harmonic Graph 3-16 Harmonic Detail 3-17 Harmonic Options 3-18 Harmonic List 3-20 3-15 Harmonic Graph Harmonic Graph The harmonic graph can be displayed by pressing Harmonics on the Home screen. The Harmonic graph display screen defaults to a graphical spectrum display, although users have the option to choose between the graph and list form. The screen will show a spectral graph featuring the amplitude of the harmonics relative to the fundamental frequency. Use the properties under the Options button to select the vertical and horizontal measurement scale. The percent magnitude of the first 60 harmonics are graphed relative to the fundamental.

The even contribution is similar for harmonics 2, 4, and 6 through N. Total value is the square root of the sum of the squares of the odd and even distortions. 3-16 CH 3/ View Real Time Data Harmonic Detail PX5 allows users to determine the numbers or the range of harmonic frequencies to Harmonic graph details trend.

The properties specified under Harmonic Options data plots apply when harmonic/interharmonic data is viewed in either graph or list form. Properties under Show Harmonics... pertain to both the graph and the list, and determine how the harmonics and interharmonics are used. If Show Harmonics... only is enabled, then only the actual harmonics are shown. If Show Harmonics... and Interharmonics is enabled, the spectrum will include all the (nominal) 5 Hz bins, which includes the actual interharmonics as well. On the graph, the harmonics are shown in the channel color, while interharmonics are shown in gray color. On the text, the harmonics are shown in boldface. If Show Harmonics... calculated including adjacent interharmonics is enabled, the interharmonics are not explicitly shown but the harmonic values include the adjacent interharmonic values in their calculation, as specified by IEC 61000-4-7. The IEC 61000-4-7 Standard specifies that the interharmonic bins adjacent to the harmonic be included in the computation of that harmonic. For example, if there was a 3rd harmonic (150 Hz) of 10%, and the value of the 145 Hz bin was 1%, and the value of the 155 Hz bin was 2%, then the value reported in the bin labelled “150 Hz” would also include contributions from the 145 Hz and 155 Hz bins. This would give 2 2 2 10 + 1 + 2 = 10.2%, not 10%. The following graphs illustrate harmonic computation as per IEC 61000-4-7 Standard.

The unit automatically turns on the correct channels, sets the parameter thresholds and waveform capture settings depending on the detected circuit type, nominal voltage and current values, and monitoring mode specified by the user. PX5 allows users to monitor events in the following setup categories: Standard Power Monitoring modes Quality, Current Inrush, Fault Recorder, Long-term Timed Recording, Continuous Data Logging, and EN50160 Power Quality mode. Selecting any setup category automatically sets trigger and capture conditions. Advanced users are free to mix and match settings (see Chapter 6 Advanced Setup Options). Standard Power Quality, Demand, Energy: PX5 algorithms automatically evaluate existing rms and waveform conditions to optimize setups to reliably capture data. This feature ensures that the first-time user gets the expected results, while providing the experienced user with the ability to tweak settings for specific applications. Either way, the necessary data used to identify critical events and optimize mitigation solutions is recorded into the data card as it occurs. Current Inrush: Determining system characteristics during current inrush conditions such as impedance changes during motor energization or the I2t curve of a breaker trip is key to preventative maintenance and enhanced power system performance. Inrush- type events such as motor start-up typically requires extended duration cycle-by-cycle recording. With PX5, users can capture and store detailed data to evaluate system performance against specifications and previous benchmark data. Under the current inrush mode, triggers are current-based. By operating in the inrush mode, the instrument will capture and store highly detailed data to a Compact Flash data card in real time, then rearm and be ready to capture data during the next test run. Fault Recorder: A fault in a wire circuit is usually due to unintentional grounding, a break in the line, a crossing or shorting of the wires, etc. A digital fault recorder logs extended duration cycle-by-cycle recording. Under the fault recorder mode, triggers are voltage-based. PX5 can help locate failures detected in various components of assorted equipment by recording an extended period of cycle-by-cycle data to capture the entire duration of the fault and the associated system response. Continued on next page 5-6 CH 5/ Start Menu Long-term Timed Recording, Demand, Energy: Performing a statistically valid power Monitoring modes quality energy survey requires the capture of a set of basic data over an extended period (continued) of time. PX5 is designed to facilitate long-term monitoring by collecting min/max/avg data at each predetermined interval in order to perform post-process harmonic and other events analysis. PX5 is also designed to be left unattended in the field, recording statistically representative data for long-term analysis. Using the Dranetz-BMI lockable portable case option or other available enclosures, power quality studies can be carried out in harsh weather environments. Continuous Data Logging, Demand, Energy: This logs the rms and power values once per second for totally gapless logging. Cyclic triggers are disabled. No waveforms are recorded under this monitoring mode. EN50160 Power Quality: EN50160 monitors and reports Quality of Supply (QOS) compliance as specified by the EN standard. The seven parameters required by EN50160 to determine QOS compliance are: Power Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply Voltage Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signalling. A full discussion on EN50160 is found on Chapter 8 Reports. The following topics are covered in this section.

Refer to Appendix B for Dranetz-BMI current probes technical specifications. 5-9 Scale Factor Setup Scale Factor Setup A scale factor is the ratio of the input to output for a particular current transformer (CT) What is a scale factor? or potential transformer (PT). A scale factor is entered in PX5 and then multiplied automatically by the measured voltage or current so the unit displays the correct values, as referenced to the primary side, rather than the secondary side of the PT or CT. NOTE: If voltage and current connections are made without using any of the above named devices, the scale factor should be set to 1. Scale factors must be entered for the following conditions: When to use • A Dranetz-BMI current probe is connected to a permanently installed CT. • The current connections are made using a Dranetz-BMI ISO box. • The voltage connections are made using a PT. Refer to the CT name plate or to the manufacturer’s literature to determine the scale Non-Dranetz equipment factor. The scale factor for a single CT or PT is calculated from its step-up or step-down ratio. Sample calculation Example of step-down ratio If a current transformer has a step-down ratio of 1000A:5A, therefore: Scale Factor = 1000/5 = 200 Example of step-up ratio If a potential transformer has a step-up ratio of 1V:10V, therefore: Scale Factor = 1/10 = 0.1 5-10 CH 5/ Start Menu After setting up current probe configurations, the Scale Factor screen is displayed.

Voltage Class: Check to select the power system that define the voltage range of distribution of the monitored system. • Standard voltage range is 16- 440 Hz. • Fast voltage range is 16-65 Hz. • Internal uses the nominal frequency when making measurements where no MARK110c reference signal is available. NOTE: Always enter a nominal frequency that matches your line frequency. This ensures that if the PX5 loses external sync, it will have a corresponding internal sync. Sync Channel: Check to specify the external sync mode to show which channel the signal is connected to. See page 5- 16 for more details on frequency synchronization. • Ch A Volts: When set to Ch A, PX5 attempts to sync to an incoming voltage signal. • Ch D Volts: When set to Ch D, PX5 only attempts to sync to voltage Ch D. Tracking Range: The Min and Max refer to the range of frequencies that the phase locked loop will “hunt” if sync is lost. See page 5-16 for more details on frequency tracking. • Press OK to accept new frequency tracking settings. • Press Cancel to quit and return to Nominal Values screen. 5-15 Nominal Values, continued Normal frequency synchronization (sync) of PX5 analog signal processing circuits is Frequency synchronization controlled by analyzing the external AC voltage signal input on channel A. Loss of external sync causes the PX5 to poll other valid voltage channels (A, B, or C) for an alternate external sync. If none exists, then internal sync is automatically selected. The frequency used for internal is entered under Frequency on the Nominal Values screen (see page 5-14). Depending on the type of circuit configuration, the instrument will attempt to autosearch to sync to any valid voltage channel. The autosearch function will be disabled when users specify sync mode Ch D Volts. Typically, external sync on Ch D is specified if it is known that signals on A, B or C are inappropriate for use as a sync source (i.e. the frequency is unstable or DC). A low distortion 50, 60 or 400 Hz signal can be input to Ch D and used as a sync signal. NOTE: Failure to connect an external sync or to select an internal sync during current monitoring will result in erroneous data being collected and displayed. Tracking determines how the phase locked loop circuitry responds to sudden changes Frequency tracking in frequency. Standard mode: On a normal power quality application [Standard], the system is designed to “ride through” voltage changes to keep tracking the fundamental frequency even in the absence of voltage. Fast mode: When operating on a local generator [Fast], the frequency will vary more as loading changes occur. The Fast mode allows the instrument to follow these changes more closely. Internal mode: In cases where no reference signal is available (such as DC monitoring), the Internal setting is used to set the sample rate. 5-16 CH 5/ Start Menu Mode of Operation After entering the correct nominal values for circuit monitoring, users have the option Basic meter setup to set the instrument to record data or to use the instrument as a meter.

It automatically saves data in the card when monitoring is on. The Compact Flash card must be installed in either data card Slot 1 or Slot 2 in order to record data. NOTE: Although PX5 is able to detect availability of data card in either slot, Dranetz- BMI strongly recommends the use of only one card slot (one data card) at a time. PX5 requires a Compact Flash data card with minimum storage capacity of 32MB, Data card size maximum of 128MB. See Appendix A Optional Accessories for the part numbers of Compact Flash cards supplied by Dranetz-BMI. NOTE: Dranetz-BMI Compact Flash data cards have been tested to work properly with the PX5. Non-Dranetz-BMI Compact Flash cards may not be compatible with the instrument and cannot be supported by Dranetz-BMI Customer Service in case problems arise. Users are advised to use only Dranetz-BMI parts and accessories. The following files are created on the data card: filename.set for setups template and Filename filename.ddb for saved events.

Guidelines on file data transfer For successful card data transfer, keep the following points in mind: • PX5 supports a maximum DOS directory size of 128MB. Minimum required Compact Flash data card size is 32MB. • Compact Flash cards allow users to store multiple files in one card. The Site name will be used as the filename for record files (i.e. if the site name is Power Xplorer Site, the filename will be Power Xplorer Site00.DDB). A number is automatically appended to the name such that filenames are automatically incremented every time the user starts monitoring with that same filename. • PX5 does not support file fragmentation. When creating a file, it will take the largest contiguous block and use that size block for data storage. Deleting files from the data card is NOT RECOMMENDED. When there is no more space available to begin new data storage, reformat the card using the PX5, after transferring data files to a computer. 5-23 Overview Section C Monitor Same Circuit Overview Menu options for monitoring become available only after setting up the instrument or Introduction from reading a setup template from data card.

Although PX5 is designed to capture data no matter what the setup is, users are able to configure combinations of setups unique to their task applications. Setup: A pre-set condition of parameter thresholds and waveform capture settings for Definitions each channel that determines what will constitute an event and what waveform data will be saved when this event occurs. Event: An event occurs when a pre-set or programmed threshold is crossed. Events result in a contiguous collection of cycles that is saved into memory. An event consists of pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s). Parameter threshold: A value that the PX5 compares to a measurement to decide if an event occurs. Also called a limit. For example, if the input voltage is measured as 135 Vrms, and the parameter threshold for voltage is 132 Vrms, PX5 saves this limit crossing to memory as an event.

Voltage disturbances which are shorter in duration than typical sags and swells are classified as transients. Two basic types of transients are: 1) impulsive transients characterized by very rapid changes in the magnitude of measured quantities and commonly caused by capacitors or inductors switching on line, loose wires, lightning, static, and power failures; and 2) oscillatory transients defined as a temporary, rapid discontinuity of the waveform. PX5 has extensive recording capabilities for low and medium frequency transients using the following trigger mechanisms: • RMS difference cycle-to-cycle • Crest or Absolute peak (Instantaneous) • Waveshape cycle-to-cycle magnitude/duration variation RMS stands for root mean square, a mathematical formula used to measure the average RMS variations voltage and current behaviors. RMS variations result whenever voltage or current behaviors rise above or fall below the programmed thresholds. See RMS Variation Limit on page 6-9 for more information on rms variations. The crest factor or instantaneous peak is the absolute peak sample value within one Absolute peak settings cycle. The instantaneous peak triggers on the absolute peak value of the entire waveform. Oscillatory transients are types of disturbances usually captured as waveshape faults. Waveform capture settings PX5 captures pre-trigger and post-trigger waveform cycles. The waveshape fault triggering algorithm essentially compares the samples for each cycle to the corresponding samples from the previous cycle. If the samples differ by more than the threshold tolerance for a length of time exceeding window percent of the power frequency cycle, a waveshape fault is registered. A trigger occurs when either waveshape or rms deviation rise above the programmed thresholds. Waveshape trigger values include the magnitude and duration of the difference between the present and previous cycle. Once a record trigger is detected, instantaneous waveform information is recorded for the prescribed voltage and current channel(s). Disturbance monitoring requires that voltage be continuously sampled, and recorded only if the signals exceed specified values. Waveshape changes are only triggerable for voltage transients as the current waveshapes are usually continually changing on a normally operating distribution system. However most types of disturbances require that current be recorded as well to help determine the source of the disturbance. 6-3 High Frequency Transients High Frequency Transients High frequency detected transients uses special circuitry to detect and capture High frequency impulsive transients as small as 1 microsecond in duration. These transients can be positive and/or transient negative values above or below the low frequency waveshape. PX5 is designed with the high speed sampling analog board that can capture voltage and current transients. Because these types of disturbances usually exhibit very narrow widths and fast rise and fall times, they are quickly damped by the system. They tend to be unidirectional when close to their source. 6-4 CH 6/ Advanced Setup Options Recording Transients PX5 uses four different algorithms to detect and record transients: Procedure to record transient • Peak or Instantaneous trigger magnitude disturbance • High frequency negative/positive peak detectors magnitude • Waveshape threshold duration or window • Waveshape threshold magnitude or tolerance Action...

Note on phase Phase settings depend upon the wiring configuration or circuit type selected under settings Setup New Circuit. For example, for wye circuits, Line-Neutral (L-N), Neutral-Ground (N-G), and Line-Line (L-L) voltage limits can be set. For delta circuits, only L-L limits can be set. 6-8 CH 6/ Advanced Setup Options RMS Variation Limit RMS stands for root mean square, a mathematical formula used to compute the RMS variation setup properties equivalent value of the voltage and current. Voltage and current changes are measured and checked against the programmed limits. Thresholds are set as high limits (threshold above the programmed limit) and low limits (threshold below the programmed limit). RMS variations result whenever voltage or current rms value rise above or fall below the programmed threshold limits. The limits determine how sensitive the instrument should be (note that statistical and trending information is always captured regardless of the limit settings, so the user will never be without a data even if he/she did not set the limits to the ideal values). PX5 allows users to set the limits for each of the triggers, as well as the amount of rms sample (cycles) to record before and after trigger cycle. In order for the instrument to trigger on rms variation, any one of the measured RMS trigger parameters quantities for which a trigger is enabled must go above the High Limit or below the Low Limit for a period of at least one rms sample point (which are taken twice per cycle with a one cycle sliding integration window). The disturbance end point is defined as the cycle when all channels for which triggers are enabled have come back within limits (plus hysteresis) for a minimum duration of Cycles specified in range to end event. Until this criteria is met, any subsequent excursions beyond the thresholds are considered part of the original disturbance. To minimize the number of triggers recorded for a sequence of closely spaced disturbances, hysteresis is employed in both voltage and time for the begin-event and end-event thresholds. NOTE: Hysteresis values assigned to limits are set by the system and not programmable by the user. 6-9 RMS Variation Limit The following parameters are required to define how an rms variation is triggered: Procedure to record rms • Low Limit variation • High Limit • Cycles in range to end event Action...

Statistical information is always captured regardless of the limit settings, so users will never be without a trend even if he/she did not set the limits correctly. The system collects data even when no disturbances occur by recording periodical statistical data (By Time). Page 6-17 shows one example of how to set entries under the Standard - Basic parameter. The same procedure applies when setting entries under other journal parameters. Page 6-18 features the list of journal parameters that can be trended. Limit methods allow users to set the threshold units by which high and low limits of Logging data by limits voltage trigger and current trigger are calculated. Thresholds are set in ranges with high limit (threshold above the normal range) and low limit (threshold below the normal range). The following threshold limits are used to trend journal parameters: Very High: specifies an absolute limit for comparison that is higher than the high limit High: specifies an absolute limit for comparison that is higher than the low limit Low: specifies an absolute limit for comparison that is lower than the high limit Very Low: specifies an absolute limit for comparison that is lower than the low limit Deadband: specifies how much a value can change before another event is recorded The Very high must be greater than High, Very low less than Low. Deadbands or sensitivity is used to record incremental changes in the parameter besides when limits are crossed. The hysteresis values assigned to limits are fixed and not programmable by the user. All limit values are used to determine if corresponding reporting or logging action should take place. PX5 is able to measure periodic samples as well as take snapshots of the voltage and/or Logging data by time current waveform. The Journal Interval menu (see page 6-22) allows users to set the time of how often the instrument will record power parameter values, demand and energy, harmonics, and flicker. Users can record data simultaneously by limits and by time. Make sure to enable the NOTE parameters to trend under Journal Categories and Journal Interval. 6-16 CH 6/ Advanced Setup Options Sample journal parameter setup Action... Result...

Power Values Definitions Power Values Interval - Power parameter values are based upon all cycles during a one second interval. Data is aggregated or summarized into min, max and avg values over the averaging period and stored at the end of the interval. Data measured include watts, power factors, as well as the one-second rms (not to be confused with the one cycle rms). Cyclic min, max and avg are based upon full cycle waveforms with a resolution of one half (1/2) cycle. They record the rms, crest, and waveshape parameters that are also used to capture a snapshot of the waveform. Note that if users did not set the thresholds for rms variations properly, the min, max and avg will still provide a record of what happened during the interval. Waveform Snapshot- Contains properties that measure periodic sample or snapshot of the voltage and/or current waveform. Users are able to determine how often the instrument will record waveform snapshots by turning the function on or off. Demand and Energy Demand Sub-Interval and Sub-Intervals per Interval - Refer to the time interval used in calculating power demand values. Demand calculations are made every sub-interval on the values that occurred during the most recent Demand Interval. Values set for Demand Sub-Interval must be an integer-divisor of the Demand Interval since the former applies when updating certain parameters of the latter. Harmonics Harmonics Journal Interval - Various harmonic parameters such as total harmonic distortion (THD), total interharmonic distortion (TID), and telephone influence factor (TIF) can be trended using periodic readings that are stored in the journal. Depending on the harmonic journal interval set, the instrument records a sampling of the waveform synchronized to the fundamental frequency, to ensure accurate calculation of harmonic phase angles. Flicker Pst (Short Term) Interval - Pst is short term perceptibility, used to set the Pst calculation interval. Typical calculation is over a 10-minute interval, though users can specify Pst Interval under Flicker. Plt (Long Term) Interval - Plt is long term perceptibility, used to set the Plt calculation interval. Typical calculation is over a 2-hour interval, though users can specify Plt Interval under Flicker. The Plt interval must be an integer multiple of the Pst interval. Sliding Plt recalculates the Plt value at each Pst interval, rather than only at the Plt interval. 6-21 Journal Interval for Timed Readings, continued The intervals for timed readings are user programmable.

The Advanced setup options for statistical package called Quality of Supply (QOS) is built into the PX5, with EN50160 monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. The EN50160-required measurement parameters include Power Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply Voltage Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signalling. The monitoring site is said to be IN COMPLIANCE if the statistical value over one (1) week for the specified parameters is 95% or greater. EN50160 Options setup allows users to define up to five mains signalling frequencies below 3 KHz. Users can also select pre-defined values for main voltage characteristics of electricity supplied by Low Voltage (LV) and Medium Voltage (MV) public networks. EN50160 is defined for the electricity supplied at the supply terminals, and does not NOTE deal with the supply system or consumer’s installation or electrical equipment itself. Since the standard deals with the voltage characteristics which can be expected in public distribution networks, other aspects essential for supply quality (i.e. short circuit power) are not treated within the scope of the standard.

Types of data display The firmware architecture of PX5 is designed to engage in various stages of acquisition, characterization, communication, and visualization of event data and journalled data. PX5 also does Quality of Supply or QOS compliance monitoring as specified by EN50160, which requires that measurement parameters must be within a specified percentage for 95% of the time. Event: An event occurs when a programmed threshold is crossed. An event consists of pre-trigger cycle(s), trigger cycle (fault), and post-trigger cycle(s). A contiguous collection of cycles caused by events is recorded into memory. An event may also contain information about other channels depending on how the user sets up the application. Trend: A trend is a graph of the value of one parameter and channel over time. Trends aim to show a macro view interface of timespan, trigger conditions, and channels of waveforms and rms that were recorded. Users can zoom in on trends for a more detailed view. The Events and Trend icons are used to view event data. Both icons are accessible at View data icons the Home page. The Events button will display event activity graphs, waveform display, event Detail magnification, and Options to change and/or add parameters/channels to plot. Buttons to view previous/next event and waveform/rms cycle display are also available. NOTE: Event data becomes available while the instrument is monitoring or by loading a previously saved file from the data card. Otherwise, a status message appears indicating that there are no event data available to view. The Trend button displays time plots or trend visualizations of journalled data. The parameters to plot consist of journal entries under the Journal Limit Setup (see pages 6-18 to 6-20). The Trend screen can display up to four plots, with a maximum of two parameters per plot. One parameter can have multiple channels to plot. Users have the option to enable/disable plot display, where display area will resize according to the number of plots enabled for display.

MARK624 7-13 Event Options Event Options A time plot is a graph of the value of one parameter and channel over time. PX5 is able Voltage and Current to display time plots for individual Voltage and Current channels (Va, Vb, Vc, Vd, Ia, channels to plot Ib, Ic, Id) or phase-to-phase Voltage channels (Vab, Vbc, Vca), depending on the available channels for Voltage and the selected circuit type. RMS variation is the most common type of disturbance and is identified as a specific RMS trigger parameters type of event by IEEE and IEC. Event characterization implemented in PX5 adheres to the IEEE 1159 and IEC 61000-4-30 Class A standards (Refer to Appendix F Event Classification). RMS values are updated at half-cycle rates, calculated over one cycle and compared against limits on a cycle-by-cycle basis. The high and low limits can be enabled and programmed individually for each phase and phase-to-phase value. The following parameters are required to define how an rms variation is triggered: Very Low limit Low limit High Limit Cycles in range to end event As per IEEE and IEC standards for multi-phase systems, the beginning of the voltage rms event occurs when any phase voltage goes outside the limits, and ends when all of the phases are within limits for an end-event number of cycles specified. This is only true for voltage, not current. In addition, rms variations can have three stages of averaging or chart rates, which is particularly useful for long duration events to save memory in exchange for reduced resolution. This mode begins if the rms value remains out of limits for longer than the post-start number of cycles that were programmed. Refer to Chapter 6 Advanced Setup Options for more information on rms variation limits. A time plot consists of the timed and threshold waveforms for the parameter on display.

The QOS functionality is equipped with monitoring and setup protocols to meet the measurements required for EN50160 monitoring. EN50160 specifies that various parameters must be within a specified percentage for 95% of the standard one week monitoring period. EN50160 will be able to display data when the instrument has been configured to EN50160 monitoring monitor EN50160 Power Quality. Refer to Chapter 5 Start Menu - Section B Wizard mode Setup - Monitoring Mode on page 5-18 for the procedure on how to turn EN50160 Power Quality monitoring on. The following topics are covered in this section. In this section Topic See Page EN50160 Measurement Parameters 8-3 EN50160 Compliance Limits 8-5 Compliance Statistical Bar Chart 8-8 Compliance History 8-11 Event Statistics 8-13 Min/Max Table for Power Frequency and RMS Voltage 8-15 8-2 CH 8/ Reports EN50160 Measurement Parameters Statistical data is calculated based on the parameters required by EN50160 for EN50160 parameters determining QOS compliance. The PX5 displays the parameters in the form of a Compliance Statistical Bar Chart. From the Reports screen, press EN50160. MARK471 The bar chart indicates the percentage of the intervals passing the specified compliance criteria. The color of the bar indicates the compliance status. A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160 Standard. See below for the description of each measurement parameter. For the QOS compliance limit values of EN50160 parameters, refer to the table of Compliance Limits on page 8-5. Power Frequency: In case of a fault operation, parts of an interconnected system may become isolated. Compliance will be assessed over an observation period of one week, by a statistical analysis carried out over the sequence of 10 seconds measurement. Frequency is represented by a single value and a single bar. The bar is a hyperlink to the Power Frequency Graph (see page 8-8). Supply Voltage Variations: Under normal operating conditions, load changes cause variations of the 10 minute average supply voltage. Generally this is compensated by automatic voltage regulation within a period of a few tenths of seconds. Supply Voltage Variations display a cluster of bars, one for each phase. The color of each bar indicates the compliance status for its phase. A green bar indicates that the parameter is within compliance. A red bar indicates the parameter does not comply with EN50160. Flicker: Typical rapid voltage changes or flicker do not exceed a magnitude of +5% or -5% of the nominal or declared voltage. This limitation is possible because connection of loads capable of creating rapid voltage changes is usually subjected to regulations. However under certain conditions, higher values of up to 10% may occur. These higher values can occur for instance in areas where high power motor equipment (blower, Continued on next page 8-3 EN50160 Measurement Parameters, continued pumps, compressors, etc.) is used. Flickers display a cluster of bars, one for each phase. EN50160 parameters The color of each bar indicates the compliance status for each phase. A green bar (continued) indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160. Supply Voltage Unbalance: The unbalance of a three phase supply voltage consists of a loss of symmetry of the phase voltage vectors (magnitude and/or angle), created mainly by unbalanced load. Compliance is verified when 95% of the sequence of valid 10 minute values are within the specified tolerance of normally 2% (in single phase/two phase supplies 3%). Supply Voltage Unbalance is represented by a single value and a single bar. The color of the bar indicates the compliance status for each phase. A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160. Harmonic Voltage: Harmonic displays a cluster of bars, one for each phase. The color of each bar indicates the compliance status that is calculated by adding the status of Total Harmonic Distortion (THD) and Harmonics 2 thru 25. The bars for Harmonic Voltage is a hyperlink to the Harmonic graph (see page 8-8). Interharmonic Voltage: Interharmonic displays a cluster of bars, one for each phase. The color of each bar indicates the compliance status that is calculated by adding the status of Total Interharmonic Distortion (TID) and Interharmonics 2 thru 25. The bars for Interharmonic Voltage is a hyperlink to the Interharmonic graph (see page 8-8). Mains Signalling: Mains Signalling is represented by a single value and a single bar. The color of the bar indicates compliance status that is calculated by adding the status of each of the defined frequencies (a maximum of five) for its phase. Users can specify the signalling frequency values under Advanced Options (see Chapter 6 Advanced Setup Options - EN50160 Power Quality on pages 6-20 to 6-21).

MARK480 Many instruments used for harmonic measurements of power supply systems express NOTE their output with reference to the fundamental component of the voltage, especially those indicating the THD factor. Harmonic and Interharmonic values are specified only up to order 25 (EN50160 limit), for the practical reason that for higher orders, the values are generally so small as to be impractical to measure. Another reason is because of the difficulty of giving values which would be relevant to all networks. 8-10 CH 8/ Reports Compliance History EN50160 provides a historical summary of the QOS compliance evaluations made. The QOS Status Summary standard monitoring period is one week, usually beginning Sunday at 00:00 (midnight). Any compliance evaluation performed in less than one week will receive an Evaluation Status marked as Incomplete, and Compliance marked as Undetermined. For completed monitoring periods, Compliance status may either be PASS or FAIL if all of the specified parameters is within limits for 95% or more of the monitoring time period. A PASS or FAIL status is hyperlinked to the Compliance Statistical Bar Chart. Compliance History displays a table that summarizes the QOS evaluation status. From Compliance History table the EN50160 screen on page 8-3, press History. The Compliance History table will appear as shown below. MARK472 scroll through previous/ PASS (green) or FAIL (red) status is linked to next items in the list the Compliance Statistical Bar Chart (p. 8-8) Evaluation Status: The EN50160-specified compliance evaluation period is a 7-day (one week) period. The evaluation status is Complete if monitoring is done within one full week, or Incomplete if monitoring is done in less than one week. An evaluation status is Incomplete under the following scenarios: • It is the current evaluation period and it has simply not completed. • It is a previous evaluation period but not enough data samples were included in the statistical analysis. This may be due to the following reasons: data was not collected or too many samples were tagged as unusable due to rms variations.

The default length of evaluation (continued) period is a 7-day week period by which the unit calculates information in strict compliance with the EN50160 standard. Compliance: Displays a PASS (green) or FAIL (red) mark if evaluation is done for a complete 7-day week period. Compliance displays an Undetermined (black) mark for incomplete periods. A PASS or FAIL compliance status is hyperlinked to the Compliance Statistical Bar Chart that shows the seven parameters required for determining compliance. See Compliance Statistical Bar Chart on page 8-8. RMS Event Count: Details of rms variation event count are shown in the EN50160 DISDIP table on page 8-13. Transient Event Count: The complete table for Transient Overvoltages appears in the EN50160 DISDIP table on page 8-14. 8-12 CH 8/ Reports Event Satistics The EN50160 DISDIP (distribution of dips) table is based upon the event statistics EN50160 DISDIP calculated by EN50160. It includes the UNIPEDE DISDIP Statistics and the table for Transient Overvoltages. UNIPEDE DISDIP data is collected and saved on a weekly basis with the counts reset as the final save occurs. If additional data is detected for an evaluation period after that period has been saved, that internal data is retrieved and updated. RMS variations shown in the UNIPEDE DISDIP table is a filtered version of the Event UNIPEDE DISDIP list. The DISDIP table includes those events of rms variation type (sags, swells, and Statistics table interruptions). From the Compliance Statistics bar chart screen on page 8-3, press DISDIP. The UNIPEDE DISDIP Statistics table will appear as shown below. MARK473 Display table for Transient Display DISDIP 3D Overvoltage (p. 8-14) Graph (p. 8-14) RMS Event Count: The table shows rms variations of specified range of magnitude and duration, also called bins. For example, an rms variation with a magnitude of 80-90% of nominal and 1-5 cycles in duration is one bin, whereas 80-90% and 10-30 cycles is another, 70-80% and 10-30 cycles is another, and so on. Each time that the characteristics of an rms variation match the criteria of the bin, the counter is incremented. RMS phenomena are typically found in bin groupings such as: • DIPS - classified in 5 Magnitudes x 8 Durations • Interruptions - classified in 1 Magnitude x 8 Durations • Temporary Overvoltages - classified in 5 Magnitudes x 8 Durations Continued on next page 8-13 Event Statistics, continued The DISDIP table also includes those events of Transient type.

FIBER OPTIC CABLE TO PX5 OPTICAL PORT DC POWER INPUT 9-5 External Communication Interface, continued When configuring both the PX5 and NodeLink® for modem communications, keep in Connection setup via mind that the PX5 uses a fiber optic serial port in order to maintain electrical isolation. Modem This means that there are no control signals available to a modem to use for handshaking and flow control. It is highly recommended that identical modems be used on the PX5 and the computer. Identical modems will have the same internal buffering and are more likely to negotiate modulation, speed, and error correction suitable to both modems. If the modems used are not identical then both the PX5 and the computer should have modems with the same chipset (i.e. Rockwell, Lucent). When configuring for modem communications, the first decision to be made is the port speed for both ends of the communications link. This is the speed at which the PX5 communicates with its modem and the speed at which the computer communicates with its modem. The same speed should be chosen for both. Ideally the speed should be at or just below the anticipated modem connect speed. Since most modems today will attempt to connect at least at 56 kbps, 38.4 kbps would be a good choice for the two port speeds. This helps to prevent possible modem buffer overflow. Follow the steps below to configure the PX5 for a port speed of 38.4 kbps. See Chapter 4 Instrument Settings - Communications for the PX5 screen interface. 1. Connect the modem to the PX5 communications adapter. 2. Turn on the modem. 3. From the PX5 home screen, click on the Preferences icon. 4. Choose Communications from the Instrument Settings Setup Menu. 5. Verify that both the Enable Communications and External Modem Connected checkboxes are enabled (checkboxes checked). 6. Check to enable 38400 under Baud Rate (bps). NOTE: The port speed of 38400 (38.4 kbps) used above may be substituted with 57600. Experiment to find the maximum port speeds that will work for the system. 7. Note the modem initialization string at the bottom of the screen. Do not exit this screen yet since you may be modifying this string after you have the Windows® modem configured. Continued on next page 9-6 CH 9/ Downloading Events NodeLink® uses Windows® TAPI when accessing modem communications resources. Connection setup via The assumption is that the Windows® modem to be used for PX5 communications has Modem been properly installed prior to executing this procedure. (continued) If the modem is not on, or was not on when Windows® was started, it may be necessary to turn the modem on and restart Windows®. Windows® searches for installed serial modems at startup. If it does not find them, it may not allow them to be configured in the Control Panel. Follow the steps below to configure the port speed for the Windows® modem in the computer: 1. Press the Start button. 2. Select Settings and then Control Panel. 3. Double-click on Phone and Modem Options. 4. Select Modems in the subsequent dialog box. 5. In the list of modems that is displayed, click to highlight the modem in question and select Properties. 6. On the General tab of the modem properties dialog box, select 38400 as the maximum port speed. 7. Click OK to exit from the open dialog boxes. 8. Close the Control Panel. It is important to note that the port speed of 38400 (38.4 kbps) may be substituted with 57600. Experiment to find the maximum port speeds that will work for the system. Continued on next page 9-7 External Communication Interface, continued Back at the PX5, the last step in configuring the modem communications is to modify Connection setup via the modem initialization string to match the modems and chipsets being used. The goal Modem is to configure for the following: (continued) • Restore factory settings. • Set auto-answer to answer on one or two rings (more than two rings are allowed but at some point the number of rings may start to conflict with NodeLink® timeouts). • Turn hardware flow control off since you are using a "two-wire" connection (fiber optic port). • Set a modem inactivity timeout of 60 seconds. The modem will hang up after one minute of continuous inactivity on the line. • Select the minimum allowable baud rate. Follow the steps below to change the modem initialization string. See Chapter 4 Instrument Settings - Communications for the PX5 screen interface. 1. From the PX5 Communications Settings screen used to configure modem connection speed, click on the Change button to the right of the string field display. 2. Use the virtual keypad that appears on the screen to change and enter the new string command. The modem initialization string commands for the Conexant (Rockwell) chipset and the Agere (Lucent) chipset are discussed in the next section. 3. When done, click on OK to accept changes in modem communications settings. The following is the AT initialization string for a modem using the newer Conexant Modem initialization (Rockwell) chipset: string command AT&F;S0=2;+IFC=0,0;S30=6 Where: AT is the modem attention command &F instructs the modem to restore factory configuration S0=2 turns auto-answer on and sets the number of rings to answer to two. +IFC=0,0 turns flow control off. S30=6 sets a 60 second inactivity modem hang up timeout. ; is a command delimiter. NOTE: It may be necessary to adjust the modem connection speeds to specify a minimum baud rate. This is possible using the +MS modem command. Check the modem manual for use of the +MS command. There are several varieties of the command. Typically, a modem modulation scheme and minimum and maximum transmit and receive speeds can be specified. Using Hyperterminal, it is possible to get a list of the possible command ranges and syntax by typing AT+MS=?. Continued on next page 9-8 CH 9/ Downloading Events The following is the AT initialization string for a modem using the Agere (Lucent) Modem initialization chipset: string command (continued) AT&F;S0=2;&K0;%E0;S30=6 Where AT is the modem attention command. &F instructs the modem to restore factory configuration.

E-15 Connecting to a Potential Transformer, continued Procedure Follow these steps to connect voltage probes to a potential transformer. Step Action 1 Turn off power to the PT. 2 Connect the colored voltage probes to the channel inputs on the PX5 top panel. 3 Connect the colored voltage probes to the PT’s connections in accordance with the manufacturer’s instructions. 4 Turn on power to the PT. The scale factor of the PT must be accounted for in making accurate voltage Scale factor measurements. Because the monitored output voltage of the PT is stepped-down (divided) from the original voltage, this ratio must be stepped-up (multiplied) by the PX5 when voltage computations are performed. The PT scale factor is usually mounted on the PT assembly and is entered into the PX5 on the scale factors screen (refer to page 5-10). Refer to the PT manufacturer’s literature for the scale factor of the device you are using. E-16 APPENDIX E/ Common Circuit Connections Connecting to a Current Transformer (CT) The following safety precautions apply to current transformer (CT) connections in Safety precautions addition to those safety precautions stated on page E-3. • Never energize a CT with the secondary open. • Never disconnect the secondary of a CT with primary energized.

Current transformers, also known as instrument transformers, reduce high level Description currents to low level currents so they can be safely monitored. These devices are similar to PTs used for voltage measurements in that both reduce values for safe measurement. The reduction, or step-down ratio, is stated as a scale factor that is used by the PX5 to step-up the measured value to its original value. There are single-phase CTs and polyphase CTs dependent on the source transformer Types of CTs used. Current reduction ratios vary widely and are also dependent on the source transformer used. Rating plates attached to the CT provide information as to the ratio and current limitations. E-17 Connecting to an Isolated Current Transformer Connecting to an Isolated Current Transformer (ISO) Low current monitoring devices made by Dranetz-BMI are called isolated current Introduction transformers or ISO boxes. The Dranetz-BMI ISO box has a 5 A current range. The following safety precautions apply to ISO box connections in addition to those Safety precautions safety precautions stated on page E-3. • Never energize an ISO box with the secondary open. • Never disconnect the secondary of an ISO box with primary energized. Physical injury or equipment damage could result if ISO boxes are improperly WARNING connected. Do not connect an ISO box between two conductors which are at different voltage potentials. Podrían producirse lesiones físicas o daños al equipo si se conectan indebidamente ADVERTENCIA las cajas del transformador aislado de corriente (ISO). No conecte una caja del ISO entre dos conductores que tengan distintos potenciales de voltaje. Une mauvaise connexion des transformateurs d’intensité isolés (ISO) peut AVERTISSEMENT provoquer des blessures corporelles ou des dégâts matériels.

The ISO box has terminal posts labeled X1 and X2 that are connected in series only Connections to ISO box with an ac current source. In normal connections, where phasing of current and voltages are important for power measurements, the X1 terminal is connected towards the source input line. Continued on next page E-18 APPENDIX E/ Common Circuit Connections When connecting to CTs, the X1 terminal is normally connected to the H1 terminal of Connections to ISO box the device for correct reference phasing. (continued) Where power measurements or voltage/current phase relationships are not important, the X1 and X2 terminals may be connected in series with the output device in any line (hot or return) or in any relationship of X1/X2. ISO boxes can be used in a number of ways. These methods include: Applications • connecting them to the secondary of CTs for metering by the PX5. • inserting them in series with the load current to measure low current values. • connecting them to a non-Dranetz clamp-on current transformer and using that CT to monitor current with the PX5. The figure on the next page shows an ISO box connected from any current channel ISO box connection to a input to a permanently installed CT. The connection shown is made in the load return current line for current monitoring only. Polarities of the ISO box and CT are kept in-phase by transformer matching markings of X1 to H1. Scale factors of both devices must be multiplied together to get the resultant scale factor. The scale factor value calculated for a CT is 3.375.
