Why the transformer rating is denoted in VA rating why not
in KW
Answer Posted / sanket patil
THE POWER FACTOR OF A TRANSFORMER FEEDING THE LOAD
DEPENDS ON THE NATURE OF THE LOAD; HENCE THE ACTIVE(P) AND
REACTIVE(Q) POWERS SUPPLIED BY THE TRANSFORMER MAY CHANGE
FOR A FIXED APPEARENT POWER(S).
HENCE THE TRANSFORMER RATING IS ALWAYS SPECIFIED IN KVA
AND NOT IN KW OR KVAR AS THEY CHANGE AS PER THE LOAD
CONNECTED TO THE TRANSFORMER.
