Power Factor Control Relay

We are offering power factor control relay.
Functions:
pfr 06pfr 12 is the new range of power factor regulators using on the highest technology and designed for easy and effective regulation. Regulator monitors the power system status and accurately and quickly takes decisions on the connection or disconnection of compensation stages in order to reach the preset target cos phi.
Regulator´s microprocessor records system voltage and current consumption of the entire operation via instrument transformer inputs and uses these to calculate the relationship between active power and reactive power in the power system. Regulator calculates the basic harmonic factor of the active and reactive currents using the fft algorithm. Thus precise measurement and control are provided even if the current waveform is distorted by higher harmonic components.
