The analyzer replaces the PQM-702.
Class A remote analysis
The Sonel PQM-710 power quality analyser is a device with extended capabilities for remote analysis in class A. Sonel PQM-710 is a power quality analyser based on advanced technological solutions, with the use of which it is possible to perform comprehensive measurements, analysis and recording of 50/60 Hz power network parameters and power quality in accordance with the European standard EN 50160 and the Regulation of the Minister of Economy on detailed conditions for the operation of the power system.
