Description

SONEL Power Quality Analyzer

A Power quality analyzer is used to measure electric power signals to determine the load’s ability to function properly with that electric power. Without the correct electric power, electrical equipment may fail prematurely or malfunction.

Thus The Sonel PQM-702 Power Quality Analyzer is a mobile, comprehensive power quality analyzer suitable for measuring electrical parameters in accordance with the standard IEC 61000 Class A. It can be used to check power quality according to various ordinances and provides a detailed overview of the system’s operation and any possible disturbances.

As a standard, the power quality analyzers are equipped with an 8 GB memory card, which allows you to collect over 4500 parameters simultaneously – at intervals of up to 200 ms. In addition to checking the power quality according to standards and ordinances, it allows you to create a detailed situation picture in terms of operation and possible disturbance.

However, nothing stands in the way to make this image even clearer – the manufacturer can expand the memory to 32 GB (optional). PQM-702 power quality analyzer control signals in power networks.The built-in GPS receiver ensures real time clock accuracy, and the integrated GSM modem facilitates remote analyzer operation.

The power quality analyzers are addressed to users who need to control power quality using a mobile device that meets the requirements of the IEC 61000 class A standard for power quality analyzers. PQM-702 fully satisfies the functional needs of power quality analysis and interference diagnostics in power networks. They are used in the field of professional energy and maintenance services in industrial plants, as well as among independent power quality specialists.
