THE DIFF. EXIST IN THE VECTORIAL RELATION.
KVA IS THE ACTUAL POWER SUPPLIED AND THE MULTIPLICATION OF
NO. OF PHASE ,PHASE VOLTAGE AND PHASE CURRENT.
WHEREAS THE KVAR IS THE REACTIVE POWER i.e. the
MULTIPLICATION OF ACTUAL POWER TO THE SIN OF ANGLE BETWEEN
VOLTAGE AND CURRENT.
KVA = 3*V*I
KVAR = 3*V*I*sin@
