Answer Posted / saqib haroon

as per my point of view,answer of the input current is
wrong. Why the respectable brother put power factore value
with KVA rating, as per formula only once we will put PF
value, which will divide this KVA rating.

In this case the answer will be
P1= 1.73*V1*I1*cosphi
2500= 1.73*13.8*I1*0.8
2500/1.73*13.8*0.8= I1
131 A = I1

Remaining portion is OK
