PFC controllers
  • In electrical engineering, the power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit, and is a dimensionless number in the closed interval of -1 to 1.Because of the costs of larger equipment and wasted energy, electrical utilities will usually charge a higher cost to industrial or commercial customers where there is a low power factor.Company ZEZ SILKO Ltd. provides complete power factor correction equipment like as capacitor bank Regulators PFR&NOVAR,vacumm Contactors for MV and capacitor contactors for LV, Reactors for inrush current and Resonance.

PFC Controller PFR6/PFR12
  • PFR 06/PFR 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.
