WebThe magnetic circuit's flux that does not interlink both windings is the leakage flux corresponding to primary leakage inductance L P σ and secondary leakage inductance L S σ.Referring to Fig. 1, these leakage inductances are defined in terms of transformer winding open-circuit inductances and associated coupling coefficient or coupling factor . WebR 1 = primary winding resistance. R 2 = secondary winding resistance. K = transformation ratio. Then, Secondary resistance referred to primary R 2 ’ can be calculated by the formula given below. R2’ = R2/K2. The equivalent resistance of transformer referred to the primary is represented by R 01. Therefore, R01 = R1 + R2’ = R1 + R2/K2.
