The parameters of a 200/400V 50HZ single phase transformer are given below: Zı= 0.2 + j0.4 N, Zz= 1.3 + jl.5 N, R,=300 N, X,=400 N and ZL= 10 + j10 N. If the primary voltage equal to the nominal value, find by using the exact equivalent circuit: (i) Input current and power factor, (ii) The load voltage, (iii) The voltage regulation, (iv) The efficiency.
