PowerVisa.qxd 8/10/06 3:55 PM Page 1 POWERVISA Power Quality Analyzer Equipped with 8 independent channels, the 3-phase PowerVisa® is the only advanced power monitoring instrument to incorporate a color touch screen into its lightweight design. Automated setups provide instant detection of circuits and configurations, ensuring that the instrument is ready to successfully collect data. Users can select the length and mode of data collection, including troubleshooting, data logging, power quality surveys, energy and load balancing. The PowerVisa collects data at 256 samples/cycle/channel, offers remote communications using RS-232, ethernet or USB options, and meets IEEE 1159 and the newest European standards. Measured Parameters (4) differential inputs, 1-600 Vrms, AC / DC, 0.1% rdg + 0.05% FS, 256 samples/cycle, 16 bit ADC (4) inputs with CTs 1-6000 Arms, CT -dependent, AC/ DC, 256 samples/cycle, 0.1% rdg + CTs, 16 bit ADC Frequency range, 10 mHz resolution, 45-65 Hz Phase lock loop – standard PQ mode Monitoring/Compliance IEEE 1159 IEC 61000-4-30 Class A EN50160 Quality of Supply Power Quality Triggers Cycle-by-cycle analysis; 256 samples/cycle; 1/2 RMS stpes L-L, L-N, N-G RMS variations: sags/swells/ interruptions RMS recordings and Waveshape recordings (30 pre-fault, 100 post -fault cycles) Low and medium frequency transients – V&I Harmonics summary parameters Cross trigger V&I channels RMS event characterization (IEEE or IEC) Distortion / Power / Energy W, VA, VAR, TPF, DPF, Demand, Energy, etc.; Harmonics & interharmonics per IEC 61000-4-7 THD/Harmonic Spectrum, TID/Interharmonic Spectrum (V, I, W) to 63rd Crest factor, K factor, transformer derating factor, telephone interference factor General Specifications Size (HxWxD): 12" x 2.5" x 8"; Weight: 3.8 lbs Operating temperature: 0 to 50 degrees C; Storage temperature: -20 to 55 degrees C Humidity: 10 – 90% non-condensing Memory options (must have one): Up to 128M removable compact flashcard PowerVisa.qxd 8/10/06 3:55 PM Page 2 Troubleshooting Harmonics The PowerVisa unique annunciator “report card” provides instant As the sensitivity of power electronics increases, equipment ranging power quality answers in the field. A wide range of power monitoring from HVAC systems, personal computers and copiers to computerized data is collected, analyzed and tabulated in color-coded categories to process equipment and manufacturing systems are susceptible to quickly identify areas of concern, which are identified in red. Drill harmonic pollution. In fact, harmonics can cause small, almost down for more detailed information by simply touching the intuitive imperceptible variations in performance that aggregate to effect graphical screen to troubleshoot problems, locate the source and significant long-term damage. Current harmonics generated by a pinpoint the root cause of power quality disturbances. source can pollute the entire power system without being affected itself. The PowerVisa captures detailed harmonics, interharmonics and subharmonics to effectively troubleshoot the complex problems caused by these events. Energy Surveys The cost of energy is oftentimes a facility’s largest operating expense. Reducing energy consumption during peak times, shifting loads, Equipment Performance Testing purchasing energy efficient equipment, or changing energy suppliers Determining the availability and compatibility of facility power can shave 10-40% annually off that cost. The PowerVisa is an prior to the installation of new equipment is simplified using the invaluable tool for performing energy surveys, including monitoring PowerVisa. The instrument incorporates advanced features such as energy consumption, usage patterns, peak demands and the activation RMS triggers, low/medium frequency transients, and cross of large loads to reduce electricity costs. Plus, the PowerVisa makes it triggering between channels to demonstrate that power mitigation easy to track and allocate energy costs by process or department. devices such as UPSs are operating properly. Real time readings observed during maintenance and startup processes enable users to see results and tweak that equipment during the testing process. 1.800.372.6832 sales@dranetz-bmi.com tel 732.287.3680 • fax 732.248.1834 • 1000 New Durham Road • Edison, New Jersey 08818 USA PowerGuide, NodeLink and DRAN-VIEW are trademarks of Dranetz-BMI. ©2003 Dranetz-BMI.
