what is reactive and active power?why we need power factor correction?
Answer Posted / cracked
reactive power - power drawn from the supply for the
excitation (production of magnetic field) of magnetic
coils/circuits of the machine.
so when using machine with large windings, consumption of
reactive power is more which leads to poor power factor and
hence power factor correction is needed.
