usually transformer rating is based on power to be drawn by
the transformer. however few factor is also play a part
like LF, DF...
For Ex say total Connected load is 820 KW
Maximum Demand would be MD= Total connected Load x L.F (0.8)
xD.F (0.7) = 820 x 0.8 x 0.7 = 459 KW
now considering the load at 0.8 leg PF the kva rating of
the transformer is
KVA required = 459 / 0.8 = 574 Kva say .......600 KVA
