Answer / shri..

KVA means Kilo Volt Ampere it is the unit of load.

KVAR means Kilo volt Ampere Reactive, it is the unit of
Reactive power.

It is used for controlling the Power Factor.

Answer / suresh

kva means kilo volt ampere it is nothing but the apparant
power that means it is the total power.
kvar means kilo volt ampere reactive it is nothing but the
wstage power.
kw means kilo watt it is nothing but the real power that
means it is the useful power.
kva is the sum of kvar & kw

Answer / gulsan goyal

KVA means Kilo Volt Ampere it is the unit of active power
as load may also require reactive power..

KVAR means Kilo volt Ampere Reactive, it is the unit of
Reactive power.
reactive power helps in flow of active power and controlls
voltage and power factor.

Answer / saranya natarajan

KVA- Apparent Power- Measured in Kilo Volt Ampere
KVA=KW cos angle
Apparent power is a function of a circuit's total impedance
(Z).


KVAR- Reactive Power-
Also called as phantom power
Reactive power is a function of a circuit's reactance (X).

KW-True Power- Measured in Kilo Watts
True power is a function of a circuit's resistances (R).

Answer / t

KVAR=KW*Power Factor

KVAR-Reactive Power

KW-Active Power.
