how we can calculate the transformer size.
Answer Posted / sachin
actually at the time of transformer rating decided the
following factor to be consider
1.Connected Load
2.Power fACTOR
3.fUTURE eXPANSION
KW=KVA*P.f
630=KVA * 0.8
KVA = 630/0.8
KVA = 787.5 KVA
So the Transformer size is 800KVA
THIS CALCULATION IS EXACTLY CORRECT
BUT FOR FUTURE EXPANTION WE CONSIDER 30 % MARGINE FOR THAT
Is This Answer Correct ? | 80 Yes | 13 No |
