Power Quality Meter/Data Logger

About BPQ Meter

Behrad power quality meter/data logger (BPQ) is an advanced metering device and datalogger which facilitates an in-depth, precise and online monitoring of power grid and electrical equipment parameters. Energy management , power quality monitoring and motor condition monitoring are in the scope of BPQ applications. BPQ with Behrad desktop, web-based and android monitoring and management softwares (BPQVision,BQMS and BPQView) can be a powerful suite for electrical engineers and manager in power industry to diagnose existing faults and predict failures in electrical installations and find the best solutions for future design.

Why is Power Quality Meter Important?

Novel monitoring systems become more essential for optimizing energy consumption in heavy industry, upgrading the quality of power and reduction of faults in high power equipment by predictive actions.

Medium and heavy industries consume lots of electrical energy, use various types of high power, high cost electrical equipment (particularly high power motors). They can affect the power system by the quality of power and amount of energy consumption at one hand and be affected by upstream power grid and its quality at the other hand. Therefore, online, precise and permanent energy and power quality monitoring of important nodes of the power grid at the incoming feeders, the local substations , transformers, electrical motors , etc. is essential in industries. Moreover, data logging over certain periods according to related standards can be used for later analysis on energy and power quality in order to achieve the best design and predictive planning.
