power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load.

The simplest way use a filter that passes current only at line frequency (50 or 60 Hz). The filter consists of capacitors or induction coils. This process is called PFC.
It means Power Factor Correction.

if there is nutral in phase why we use earthing wire and grounding? even at fault condition the fault current flows to neutral (it is a lower path)
