It provides an accurate measurement, voltage and current 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. PQM4000 is available in 2 models: one for external standard CTs with 1 or 5A output and another one for current clamps with 1 or 3V ouput. In this way maximum flexibility is granted 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 or transfer it to an USB flash drive. PQM4000 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. An additional RS485 port gives the possibility to interconnect the device with slower monitoring systems, such as PLC. The integrated GPS receiver 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. It is provided with a high resolution TFT display with touch screen which allows a fast and direct instrument management. User-friendly multilingual interface is common to its web server, very useful for on-site instrument operations. Additional voltage and current measurement channels in comparison with other standard three-phase devices. Current inputs for CTs or for clamps to grant an accurate current measurement. Continuous monitoring of the power quality and Class A certified measurements for voltage and current characteristics. Simultaneous recording of events, Min/Avg/Max LOG and energy counters. Several possibilities for instrument data transmission: Ethernet, WIFI, Modbus RTU/TCP, USB. User-friendly instrument web interface with multilingual pages.
