Upgrading Older Capacitor Banks is Important As an inexpensive source of reactive power, capacitor banks bring many benefits to a facility. They are widely deployed to avoid penalties on utility bills, lower distribution losses, increase transformer/Genset capacity, maintain nominal voltage, and to reduce energy losses resulting in decreased carbon emissions. When coupled with reactors, capa...

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...

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...
