An example of how to calculate the capacity of reactive power (kVAr)? An Motor is supplying a load of 700 kW at a P.F (Power factor) of 0.65. What size of Capacitor in kVAr is required to raise the P.F (Power Factor) to unity (1)? And how many more kW can the motor supply for the same kVA loading when P.F improved. Supplying kW = 700 kW Original P.F = Cosθ1 = 0.65 Final P.F = Cosθ2 = 1 θ1 = C...

Benefits by installing power factor correction systems? Power factor correction systems provide much benefit: Reduced electricity utility bills Your electric utility provides working (kW) and reactive power (kVAR) to your plant in the form of apparent power (kVA). While reactive power (kVAR) doesn’t register on kW demand or kW hour meters, the utility’s transmission and distribution system must be...

Power capacitors are very beneficial in power networks. They provide reactive power required by motors, transformers, etc. This increases the transmission capacity and reduces losses thanks to higher power factors. They enable the power factor targets of the utilities to be met. Power capacitors and series reactors are also a key component in various filter solutions that reduce harmonic cont...

ZDDQ-SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power. It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation's non-useful power (inductive and capacitive), thus ensuring that the target cosϕ is achieved. ZDDQ SVG instantly compensates and adjust...
