Answer / rgs

GENERALLY TRANSFORMERS& GENERATORS ARE SUPPLIED WITH KVA
RATING AS LOAD POWER FACTOR IS NOT KNOWN.

kW = kva x pf

Prsently assuming rated voltage to be 415 v

A = 60 x 1000 / 415 = 144.

If there are two transformer having rating of 2.5mva, 6.6kv/440v(satr-star),and the load is 600kw then what is better to maintain less losses in transformer having both transformer in parellel or only single transformer connected to load? Please give calculated answer
