The parameters measured for a 220V/110V, 50 Hz, single-phase transformer are:
Self inductance of primary winding = 45 mH
Self inductance of secondary winding = 30 mH
Mutual inductance between primary and secondary windings = 20 mH
Using the above parameters, the leakage (Ll1, Ll2) and magnetizing (Lm) inductances as referred to primary side in the equivalent circuit respectively, are
