Answer / arulkumaran

POWER FACTOR = 0.85 (APP)
KVA = KW/PF
KVA = 75/0.85
KVA = 88.235
SO,average kva of auto transformer 90KVA (APP)

Answer / baikunth

motor rating in kva = 75/0.5=150kva
so the apparent power is let 200kva.
Keeping the starting condition and fault conditions like
overload,single phasing etc. I suggest 200x3=600kva or
750kva a standard value for the motor of 75kw,supposing that
transformer ration is 1:1.

purpose of check value
