All quantity are shown in diagram after that we have to draw The no load current I0 is divided into, pure inductance X0 (taking magnetizing components Iμ) and non induction resistance R0 (taking working component Iw) which are connected into parallel across the primary. The value of E1 can be obtained by subtracting I1Z1 from V1. The value of R0 and X0 can be calculated as, R0 = E1 / Iw and X0 = E1 / Iμ. But, using this equivalent circuit does not simplifies the calculations. To make calculations simpler, it is preferable to transfer current, voltage and impedance either to primary side or to the secondary side. In that case, we would have to work with only one winding which is more convenient. From the voltage transformation ratio, it is clear that, E1 / E2 = N1 / N2 = K Now, lets refer the parameters of secondary side to primary. R2 can be referred to primary as R2',Now, refer the parameters of secondary side to primary.X2 can be referred to primary as X2' , refer the parameters of secondary side to primary. RL can be referred to primary as RL',Now, refer the parameters of secondary side to primary.XL can be referred to primary as XL', refer the parameters of secondary side to primary.E2 can be referred to primary as E2', refer the parameters of secondary side to primary. V2 can be referred to primary as V2' and Now, lets refer the parameters of secondary side to primary.I2 can be referred to primary as I2' and draw equivalent circuit of single phase transformer as the values of winding resistance and leakage reactance are so small that, V1 and E1 can be assumed to be equal. Therefore, the exciting current drawn by the parallel combination of R0 and X0 would not affect significantly and draw equivalent circuit of single phase transformer Approximate Equivalent Circuit Of Transformer If only voltage regulation is to be calculated, then even the whole excitation branch (parallel combination of R0 and X0) can be neglected. Then the equivalent circuit can be drawn.
