THE CAPACITY OF TRANSFORMER USED FOR SITE APPLICATION SHALL
BE CALCULATED BY FOLLOWING CONSIDERATION;

CAL.TOTAL CONNECTED LOAD
BASE ON KW & ASSUMATION OF 0.8 P.F.
CAL. THE KVA/ MVA RATING OF X'MER I.E. KW/0.8
AFTER GETTING KVA/MVA ADD THE 20% IN CAL.KAV/MVA

I.E. KVA/MVA + 0.2*KVA/MVA

20% EXTRA AS PER IEEE RULE

AS PER IEEE NORM ,UR TRANSFORMER SHOULD BE LOADED AT 80% OF
UR FULL CAPACITY OF UR TRANSFOMER.

I HOPE ABOVE INF. IS SUFFICIENT.
