APFC in Electrical Systems

APFC panel in Electrical System

 APFC stands for Automatic Power factor correction/Controller.

APFC Panel used in electrical power distribution system to improve the power factor from lagging PF to near to unity PF.

Power factor is the ratio of active power to the apparent power .It is denoted by cos Pi

Cos Pi = KW/KVA

Where

 KW is equals to 1.732 x V x I x Cos pi (or) V x  I x Cos pi

KVA is equals to V x I
