Importance of REACTIVE POWER:
Electrical machines work on the principle of conversion of
electromagnetic energy.A part of input energy is consumed
for creating and maintaining the magneticfield.This part of
the input energy cannot be converted into active energy and
is returned to the electrical network on removal of the
magnetic field. so this requirement of magnetic field by
machines is met by REACTIVE POWER.
what happens when reactive power is ZERO.
when the connected load to the system is purely Resistive
reactive power generation vl b ZERO.
