Transformer rating already given=2000KVA
Select Air circuit breaker ie secondary current multiplying with 1.6A to the rating of the transformer.
secondary current = 2000×1.6
= 3200A Air Curcuit Breaker Required.
since 1KVA =1.6A
how to find out primary current.
the relation ship between voltage and current.
V2/V1=I1/I2
415/11000=I1/3200
I1=120A...
