The PXe-PQA4000 Power Quality Analyzer monitors and records all major power quality events and parameters. It provides an accurate measurement of events and disturbances affecting Power Quality and usage, based on its voltage and current measurement according to Class A specification.
The PQA simultaneously measures consumption and demand as it captures harmful events and faults. It is 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 Inter-harmonics, 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.
The PXe-PQA4000 is available in 2 models:
One for external standard CT’s with 1 or 5A output and another model for current clamps, conventional and flexible types. In this way maximum flexibility is granted even on existing plants – requiring retrospective monitoring . The powerful recording features allow capture and recording of all types of power measurement and PQ data simultaneously. All this information can be recorded for long time periods 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 in different ways: users can download them directly through a web interface or set an automatic scheduled data upload to a remote server or transfer it to an USB flash drive. The PXe-PQA4000 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 and maintenance operations. An additional RS485 port gives the possibility to interconnect to monitoring systems such as a 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 for fast and direct instrument management. A User-friendly multilingual interface is common to its web server, very useful for on-site instrument operations.
