The power required to run a pump using a motor is active or
real power(KW).
The inductive nature of the motor windings will impose a
power whose current flow direction will be, for one half
cycle it flows from supply to motor and in the next half
cycle it flows from motor to the supply. Hence it is called
circulating current. It just flow TO and FRO between the
supply point and the motor. The power of this circulating
current is called as reactive power(KVAR).
Also this is the reason why electricity board charge us for
KW power and not for KVAR power.
