For the simple and easy understanding,power factor is the Alternating current ( AC ) value of electrical efficiency.The ratio of true power flow into load of apparent power.Power Factor is the ratio of Working Power to Apparent Power.If equipment or machine running in maximum efficiency,we can save the electric cost and keep the long life span.

The range of power factor is between 0 and 1.Normally it state in percentage value e.g :  85 % pf.In power distribution,It in two condition of power factor,Leading or Lagging otherwise Inductive or Capacitive.They required the minimum level of power factor ( pf ) between 0.80 until 0.85 ( 80% – 85% ).If not they imposed surcharge to the owner of installation. read more
