Quality Analyzer PQM3000 Overview
The PQM3000 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 an 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.
PQM3000 is available for external standard CTs with 1 or 5A output. 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 a 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: users can download them directly through a web interface or set an automatic scheduled data upload to a remote server.
PQM3000 includes different communication ports so the user can access them 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 external mobile network router gives the possibility to manage the device by using a 4G network if the
Ethernet communication is not available (router sold separately). The RS485 port is dedicated to the 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. A user-friendly multilingual interface is provided for the webserver which simplifies the full access to instrument operations.
