IF we have 500kva transformer 11.0/0.415V, 50Hz. How to
calculate the current on HT & LT side, how can we consider
for its breaker (HT & LT both)? You are requested to solve
the question herewith.

Answer Posted / a.i.a

As, usually the ultimate load current for any distribution system take 20% spare loads for future , so full load current shall be multiplied by 0.2 more (i.e 1.2) to calculated MCCB rating.


hope you got the correct answer.
