Answer / prof. nazar m. karyar

KVA is the apparent power of an electrical load (refer to
the power triangle diagram),it means the voltmeter reading
times the Ammeter reading of the electrical load. KWh is the
electrical energy consumed by the electrical in certain
hours of time

Answer / laxman murmu

kva means kilo volt ampere.the transformer,alternator rating
are measured by kva.khw means kilo watt hour.it is the unit
of electrical energy.

Answer / keshav

Both are unites of power.
KWH=KVA X power factor.
or KWH=KVA X PF
If power factor is not given, it is assumed to be 0.8
KWH is the actual power that is available and can never be more than KVA.
For pure resistive load, KWH=KVA as Pf is unity in this case.

Answer / bala

KVA-it means Kilo Volt Ampere.it is unit of transformer.
KWH-it means Kilo Watt per hour.it is the unit of power.

i am using auto transformer for starting of induction motor to provide reduse voltages...but the principle of a tansformer according to definition"which transform energy to on circuit to another circuit with constant power and constant frequency". so if i am using reduse voltage then current obsely hige because power is same.but we use auto transfarmer for starting of induction motor to give low current.but here according to definition we are giving hige current.
