Power Quality Analyzer PQM3000 – Overview

The PQM3000 is a high-end power quality analyzer which is able to monitor and record the major power quality parameters. It provides accurate measurement and voltage characteristics are monitored according to Class A specifications. It can also act as an event/fault recorder, capable of storing 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, and Mains Signalling. It also provides standard power measurement data for three-phase systems. Extra voltage and current measurement channels allow additional monitoring of 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 in existing plants.

The powerful recording features can capture and record all types of standard and PQ data simultaneously. This can be recorded for a long time due to the high memory capacity. In this way a complete EN 50160 analysis can be performed. Events and disturbances also provide waveform recording together with RMS values. Recordings can be transferred directly through a web interface or set as 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 such as web access for real-time monitoring, device setup, stored data transfer, and maintenance operations. The external mobile network router gives the possibility to manage the device via 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 of the installation 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 access to instrument functions.
