Answer / rishu chaubey

reactive or apparent power is that which depend upon the
magnitude of voltage at both receiving and sending end.It is
a useless power you would not normally be charged for using
reactive power because you are consuming some energy half
the time, and giving it all back the other half of the time.
generally reactor are used to consume reactive power.

hi; i am sorry i forget my mial (elmalt88@yahoo.com)

Answer / muthukumar

We can control the power factor by switch on and off the
capacitor. Reactive power is nothing but capacitive power.
by using capacitive power continuosly the winding, core
gets heat and it will damage the equipment.
KVA= KW+KVAr

KVA---- Apparent Power
KW----- Active Power
KVAR--- Reactive Power

Reactive Power is full of losses. If we use any electrical
equipment automatically reactive power obtained due to core
losses and iron losses

Answer / vinothbabu.k

THE POWER WHICH REAL UTILISATION OF THE MOTOR R OTHER
EQUIPMENT CALLED AS ACTIVE POWER.BUT THE POWER CONSIDERING
WITH LOSSES LIKE IRON LOSS,CU LOSS,FRICTION LOSS WEAR TEAR
LOSS COMBINING THIS LOSSES WITH THE ACTIVE POWER CALLED AS
REACTIVE POWER,ITS SIMPLY SAY THE POWER DELEVARED IN THE
OUTPUT...
IT CAN CONTROL BY AVOIDING ALL THIS LOSSES
