Class A rack 19” power quality analyzer with Rogowski coils • • • • • • • • • • Rack 19” mounting Current inputs for direct connection of Rogowski coils Harmonics and interharmonics measurement Data recording for further EN 50160 analysis Data recorded in standard PQDIF and CSV file formats Embedded web server Communication on Ethernet and 3G networks Included external GPS module for accurate timing Internal rechargeable backup battery Certified according to IEC/EN 61000-4-30:2015 Ed.3, Class A for voltage characteristics » General features PQM3000RGW is a high-end power quality analyzer, able to monitor and record the major power quality parameters. It provides an accurate measurement, voltage characteristics are monitored according to Class A specification. At the same time it acts as event/fault recorder, capable to store a high number of voltage events and disturbances, frequency variations, inrush current, etc. Additional PQ data can be recorded, such as Flicker, Unbalance, Harmonics and Interharmonics, Mains Signalling. It also provides standard power measurement data for three-phase systems. Extra voltage and current measurement channels give the possibility to monitor Neutral Potential and Earth Leakage current. Innovative Rogowski coils are included together with the instrument to grant a complete measurement system as well as quick installation. Their current full scale can be programmed among three default values, simply selectable in the device setup, to ensure maximum flexibility even on existing plants. The powerful recording features give the possibility to capture and record all types of standard and PQ data simultaneously. All this information can be recorded for long time period due to the high memory capacity, in this way a complete EN 50160 analysis can be performed. Events and disturbances provide also waveform recording together with RMS values. Recordings can be transferred in different ways: user can download them directly through web interface or set an automatic scheduled data upload to a remote server. PQM3000RGW includes different communication ports so the user can access it in different ways. The Ethernet ports on the front and rear panels allow complete control on the instrument: web access for real-time monitor, device setup, stored data transfer, maintenance operations. The integrated mobile network router gives the possibility to manage the device by using 3G network if the Ethernet communication is not available. The RS485 port is dedicated to data reading of PQMGPS1, i.e. the external GPS module provided with the instrument. PQMGPS1 provides accurate time information regardless of the location where the meter is installed in a distributed monitoring system. Moreover, different I/O channels are provided to enhance the instrument features. An user-friendly multilingual interface is provided for web server which simplify the full access to instrument operations. Additional voltage and current measurement channels in comparison with other standard three-phase devices. Rogowski coils included to grant a quick installation as well as an accurate current measurement. Continuous monitoring of the power quality and Class A certified measurements for voltage characteristics. Simultaneous recording of events, Min/Avg/Max LOG and energy counters. Several possibilities for instrument data transmission: Ethernet, Modbus TCP, 3G network. User-friendly instrument web interface with multilingual pages. Power monitoring & control systems Switchboards, gensets, motor control centers, etc. Individual machine load monitoring Power demand analysis and management Harmonics monitoring Remote metering and cost allocation Motor inrush current studies » Related products • • • • MFC150 Rogowski coils PQMGPS1 external GPS module PQM-Tool Class A monitoring software tool PQM-Analyzer for data
