Answer Posted / khalid hussain shaikh
POWER=1.732*VOLTAGE*CURRENT*POWER FACTOR
HERE POWER=2500KVA
VOLTAGE=11 KV
POWER FACOR AS STANDARD=0.85
I=?
I=2500KVA/1.732*11KV*0.85
KV CANCELLED EACH DENOMINATOR AND NUMARATOR,
I=2500/1.732*11*0.85
I=154 AMP (11 KV SIDE)
I=2500 KVA/1.732*415 V*0.85
V CANCELLED EACH DENOMINATOR AND NUMARATOR
I=2500 K/610.963
I=4.091 KA
I=4091 AMP
