What's the Definition of Power Factor? Power Factor Definition: Power factor(PF for short) is the ratio between KW and KVA drawn by an electrical load where the KW is the actual load power and the KVA is the apparent load power. It is a measure of how effectively the current is being converted into useful work output and more particularly is a good indicator of the effect of the load current on th...

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...
