It is meant to make sure that the basic procedural issues on power monitoring are explained and understood to minimize the learning curve. The procedures below are discussed in detail in the next chapters. Starting A New Session: 1. Reset To Factory Configuration [Memory Functions] NOTE: Skip this step if you wish to maintain Input Configurations and Thresholds. 2. Make sure unit is set to Auto-transfer Disabled [Memory Functions] 3. Make sure Monitoring is Off [Setup Menu] 4. Clear Event Memory [Memory Functions] 5. Insert Memory Card (If you are using one) 6. Format Memory Card [Memory Card Functions] NOTE: All data on card will be lost. Save important data on computer hard disk. 7. Set desired Site Name [Set Programmable Features] 8. Set Memory Mode: [Memory Functions] Fill and Stop: Monitoring will stop when Internal Memory fills up. Does not take advantage of Memory Card. Overwrite: Internal memory will overwrite old data as it fills. If auto-transfer is enabled, card will fill until full and then stop. Card will not overwrite. Internal memory will continue to overwrite when card is full. NOTE: Overwrite is recommended with Memory Card use. 9. Run Easy Start [Setup Menu] You will need to know a) circuit type, b) the nominal measurement voltage, c) which current probe you are using, and d) nominal current. NOTE: PT and CT setup are beyond the scope here, refer to User’s Manual. Power Platform-PQ Plus Quick Reference Guide 1 Impatient’s Guide to Power Monitoring 10. Set Waveform Capture [Advanced Setup Options][Set Thresholds] Make sure Waveform Capture is ON-ON for all the parameters important to you. At least V Hi, V Lo, I Hi, I Lo, V Trans, I Trans. 11. Set Waveform Capture for Timed Events [Advanced Setup Options] [Set Input Configurations] This is recommended for problem analysis but will consume memory. 12. Enable Auto-transfer to Memory Card [Memory Functions] This may take several minutes with a 4 meg card. The unit is setting up the auto transfer file on the memory card called {sitename}.mdb. Available space will read minimal even though the card is empty. NOTE: NEVER change the site name after enabling auto-transfer. You will not collect data. 13. Check Meter Mode and make sure the measurements make sense. 14. Check the Phasor Diagram and make sure it matches the diagrams shown in this Quick Reference Guide for your specific circuit type. 15. Clear Event Memory 16. Turn Monitoring on 17. Check View Data after 15 to 30 minutes Check Time Plots View Events by Number. If you see a number of events of the same type you have either solved the power problem or you may need to adjust the Threshold. Power Platform-PQ Plus Quick Reference Guide 2 Introduction & General Description 1 Power Platform PP1 and TASKCard PQPlus The Dranetz-BMI Power Platform introduces a new concept in power monitor- ing equipment by allowing you to change the type of monitoring the unit does by changing a TASKCard. A TASKCard is a removable memory card that is installed in the rear panel of the Power Platform and contains an operating system that is designed for a specific application (task). The PQPlus TASKCard, shown below, changes the Power Platform to a power quality monitor so that it can record sags, swells, transients, outages, plus demand, energy and harmonics. Unpacking the Unit Unpack the Power Platform from the carton as follows: 1. Remove any remaining literature inside the top of the carton. 2. Carefully remove the Power Platform from its shipping carton. 3. Remove all accessories inside the carton. Check that the Standard Accessories are included. Pages 65-66 list the Part Number and Description of the Standard and Optional Accessories. 4. Place all of the shipping materials back into the carton, close its flaps, and store it away. DO NOT throw away the carton and packing materials. Save the carton and packing materials in case you have to return the Power Platform to Dranetz-BMI for maintenance, repair, or calibration.

This kit, Part Number 155520, contains adhesive backed color-coded marker labels to attach to the probe handle and the plug end of the probe. Use red label for channel A, yellow for B, and blue for C. Channel D is left unmarked. See figure below for proper wire marker placement. Wire marker placement 8600-62.pcx Connection Guidelines Each probe has a polarized plug to fit any one of the four current input connec- tors (A, B, C, or D) on the rear panel of the Power Platform. An arrow marking on the handle is a guide to ensure that you position the probe with the arrow pointing towards the load. Correct position of the probe is necessary for correct power measurements. Follow these guidelines when making current connections. · Position the probe with the arrow on the handle facing the load. · For greatest accuracy, use a probe that is rated at no more than twice the nominal value you expect to measure. See figure next page showing how to connect a current probe to channel A for current monitoring of a single phase line. Power Platform-PQ Plus Quick Reference Guide 17 Cable Connections 2 Sample Single Phase Connection The current probe may be connected to the return line if desired to measure the return current when checking for load current leakage, loop current relation- ships, etc. LINE LOAD LOAD NEUTRAL RETURN GRN RED SOURCE SAFETY GROUND 8600-20 NOTE: The connection shown above is not recommended without a voltage connection to ensure frequency synchronization. Power Platform-PQ Plus Quick Reference Guide 18 Cable Connections 2 Connecting to a Current Transformer Current transformers, also known as instrument transformers, reduce high level 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 PP1-PQPlus to step-up the measured value to its original value. Safety Precautions The following safety precautions apply to current transformer (CT) connections in addition to the Safety Precautions stated on page 9. · Never energize a CT with the secondary open. · Never disconnect the secondary of a CT with primary energized. WARNING: Refer to the manufacturer’s instructions related to the CT for exact information on connections for current monitoring. Do not exceed manufacturer’s ratings. Potential transformers are not manufactured by Dranetz-BMI. Types of CTs There are single-phase CTs and polyphase CTs dependent on the source transformer 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. Power Platform-PQ Plus Quick Reference Guide 19 Cable Connections 2 Connecting to an Isolated Current Transformer (ISO) Low current monitoring devices made by Dranetz are called isolated current transformers or ISO boxes for short. They are typically used to monitor the output of existing CTs. Dranetz makes two types of ISO boxes; one model (ISO-1A) monitors up to 1 amp rms of current maximum, the other model (ISO-5) up to 5 amps rms maximum. Both are available as optional accessories. Safety Precautions The following safety precautions apply to current transformer (CT) connections in addition to the Safety Precautions stated on page 9. · Never energize a CT with the secondary open. · Never disconnect the secondary of a CT with primary energized. WARNING: Physical injury or equipment damage could result if ISO boxes are improperly connected. Do not connect an ISO box between two conductors which are at different voltage potentials. Connection Guidelines ISO boxes can be used in a number of ways. These methods include: · connecting them to the secondary of CTs for metering by the PP1-PQPlus · 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 PP1-PQPlus. See figures displayed in the next pages showing the different ways to connect ISO boxes. Power Platform-PQ Plus Quick Reference Guide 20 Cable Connections 2 Sample ISO box connection to a current transformer The figure below shows an ISO box connected from Channel B current input to a permanently installed CT. Polarities of the ISO box and CT are kept in-phase by matching markings. Scale factors of both devices must be multiplied together to get the resultant scale factor. 8600-24 Power Platform-PQ Plus Quick Reference Guide 21 Cable Connections 2 Sample ISO box in-line connection The figure below shows the ISO box connected in series with the load of a single-phase line. The connection is made with the X1 terminal connected to the source input line and X2 connected to the load line. The scale factor is that of the ISO box only. 8600-25 Power Platform-PQ Plus Quick Reference Guide 22 Cable Connections 2 Sample ISO box connecting to a non-Dranetz current probe The figure below shows the ISO box connected to a non-Dranetz clamp-on current transformer. In this case the scale factor is the product of the ISO box and the CT. Refer to manufacturer’s literature to determine the CT scale factor. WARNING: Refer to the manufacturer’s instructions related to the CT for exact information for connections for current monitoring. Do not exceed manufacturer’s ratings. 8600-26 Power Platform-PQ Plus Quick Reference Guide 23 Cable Connections 2 This page intentionally left blank.

Power Platform-PQ Plus Quick Reference Guide 34 Circuit Types & Predefined Setups 4 This chapter shows the various circuit type connections of voltage and current probes that are required when power measurements are to be made. It features the threshold and waveform capture settings for the ten setups on the PQPlus TASKCard that correspond to each circuit configuration. Circuit Connection Diagrams, Phasor Diagrams, and the Predefined Setups Corresponding to Each Circuit Type Circuit Types The Dranetz-BMI PP1-PQPlus can monitor any of the following power configurations: Single phase, 2 wire Split phase, 3 wire 3 phase, 3 wire (delta) 3 phase, 4 wire (wye) While monitoring any of the above configurations, the Power Platform can also be wired to monitor neutral to ground voltage and neutral current. Phasor Diagrams Each circuit type is followed by a diagram describing the voltage and current phasors (for resistive loads) for standard type of power connections. Phasor diagrams are graphic representations that show the magnitude and angular relationship of each phase of a monitored connection. Predefined Setups A setup is a list of parameter thresholds that controls the events that the PP1- PQPlus records. The PP1-PQPlus has 10 setups. Setups 1 through 9 are pre- defined but can be modified. Setup 10 is used for Easy Start and can not be modified, but can be copied and then modified. In the next pages, circuit connection diagrams are displayed, followed by the voltage and current phasors, then the default settings of the predefined setups using a particular power connection type. If you are making power measurements, follow these diagrams so that your ABC totals are calculated correctly. Follow all Warning advisory and Safety Precautions listed next page. Power Platform-PQ Plus Quick Reference Guide 35 Circuit Types & Predefined Setups 4 WARNING! To reduce the risk of fire, electrical shock, or physical injury it is strongly recommended to fuse the voltage measurement inputs. DO NOT fuse any ground connection. Fuses must be located as close to the load as possible to maximize protection. WARNING! For continued protection against risk of fire or shock hazard replace only with the same type and rating of recommended fuse. Use only fast blow type fuse which is rated 600 V. Recommended fuse type is Littelfuse, part number KLKDO.25 rated 600 V AC/DC, 0.25 A fast blow. WARNING! Do not replace fuse again if failure is repeated. Repeated failure indicates a defective condition that will not clear with replacement of the fuse. Refer condition to a qualified technician. Safety Precautions · Connect the green safety (earth) ground first, before making any other connections. · When connecting to electric circuits or pulse initiating equipment, open their related breakers. DO NOT install any connection of the instrument on live power lines. · Connections must be made to the instrument first, then connect to the circuit to be monitored. · Wear proper Personal Protective Equipment, including safety glasses and insulated gloves when making connections to power circuits. · Hands, shoes and floor must be dry when making any connection to a power line. · Make sure the unit is turned OFF before connecting probes to the rear panel. · Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if defective.

Power Platform-PQ Plus Quick Reference Guide 60 Memory Card Operations 5 A memory (data) card is used with the Power Platform to provide a removable, rugged, compact, solid state mass storage device. A memory card, shown below, uses low power, has an internal battery for data retention, and is available as an optional accessory in sizes from 512 Kbytes to 4 Mbytes. The PP1-PQPlus treats the memory card like a floppy disk storing files in a DOS format. In the PP1-PQPlus, the memory cards are used to store events and setups. 8600-64 Entering a Site/File Name This function allows you to enter a site name of up to 20 characters. The site name appears on printouts. The site name is also used for file names on the memory card. NOTE: NEVER change the site name after enabling auto-transfer. You will not collect data. How to Enter a Site/File Name 1. Select item #3, Setup Menu, from the Main Menu. 2. Select item #2, Set Analyzer Parameters, from the Setup Menu. 3. Select item #1, Set Site/File Name, from the Set Analyzer Parameters Menu. Result: The following screen will appear.

Setting Memory Storage Mode The memory storage mode affects how events are saved to internal memory. There are two settings: ‘Fill and Stop’ and ‘Overwrite’. Fill and Stop mode When in Fill and Stop mode, the PP1-PQPlus saves events until memory is full, then stops saving new events. All events in memory will be preserved. Overwrite mode When in Overwrite mode, the PP1-PQPlus will save events normally until memory is full. After that, the PP1-PQPlus will replace the oldest events in memory with new events. This mode sacrifices old data in order to continuously save the most recent events. Power Platform-PQ Plus Quick Reference Guide 62 Memory Card Operations 5 How to Change the Memory Storage Mode setting 1. From the Main Menu, select item #3, Setup Menu. 2. From the Setup Menu, select item #7, Memory Functions. 3. From the Memory Functions menu, select item #4, Set Memory Storage Mode. Result: The following screen will appear. 4. Press NEXT MODE to change present configuration to Overwrite. 5. Press EXIT to enable Overwrite configuration and return to Memory Function screen. Setting Auto-transfer to Memory Card The auto-transfer function allows you to set the PP1 to automatically copy events from internal memory to a file on a memory (data) card. This allows you to take advantage of the larger storage capacity of a memory card (for 1 Mbyte or larger cards). Settings: There are two auto-transfer settings: ‘Update Continuously’ (enabled) and ‘Do Not Auto-transfer’ (disabled). NOTE: To fully take advantage of the auto-transfer function, the memory storage mode should be set to Overwrite. See previous page about this setting. Update Continuously When the auto-transfer mode is set to Update Continuously, the PP1-PQPlus will continuously store new event data to the memory card as well as to internal memory. Do Not Auto-transfer When the auto-transfer mode is set to Do Not Auto-transfer, events will be saved to internal memory only. Power Platform-PQ Plus Quick Reference Guide 63 Memory Card Operations 5 Auto-transfer file Size: The file will be as large as the available free space on the memory card. Filename: The filename for the auto-transfer file is filename.mdb. Where filename is the first eight characters of the Site/File Name. See pages 61-62. Overwrite mode: When the memory storage mode is set to Overwrite, the auto- transfer file will also Overwrite, independently of internal memory. How to Change the Auto-transfer setting 1. From the Main Menu, select item #3, Setup Menu. 2. From the Setup Menu, select item #7, Memory Functions. 3. From the Memory Functions menu, select item #2, Auto-transfer Options. Result: The following screen will appear. 4. Press ENABLE CONT or DISABLE XFER to change the auto-transfer mode. 5. Press EXIT to enable auto-transfer. NOTE 1: NEVER change the site name after enabling auto-transfer. You will not collect data. NOTE 2: When auto-transfer is enabled, events in memory will immediately be transferred to the memory card and the message “Auto-Transfer in Progress. Please Wait.” will be displayed. The DATA CARD indicator will light when data is being transferred to the memory (data) card.
