Answer / gova

Hi

If it is a single phase tfr,then (Voltage*current)/1000 =
KVA

If it is a three phase tfr,then
(1.732*voltage*current)/1000 = KVA

Cheers

Answer / mahesh sali

U KNOW THAT

KVA = 1.732*V*I

IF U KNOW THE ABOVE VARIABLE , THEN U CAN EASILY FIND THE
KVA RATING OF TRANSFORMER

THANKING U

Answer / veeru

thats a silly question yar
we know power=v*i for single phase
power=3vi where v&i are line parameters

Why we have short circuit the secondary of the transformer
