A 100-KVA, 1100/220 V, 50 Hz, single-phase transformer has a leakage impedance of (0.1 + j0.4) ohm from the H.V. winding and (0.006 + j0.015) ohm for the L.V. winding. Find the equivalent winding resistance and reactance referred to the H.V. and L.V. sides. #electricalengineering #education #tutorial
