3. A 220 V /345 kV, 200 kVA testing transformer to be used for cable testing has 10% leakage reactance and 2% resistance. The cable has to be tested at 600 kV, 60 Hz while charging current is 0.5A. Find the required value of the series inductor to be connected with the transformer to achieve resonance. Assume (Rind =1.8% of Xind). Find the primary voltage of the transformer during this test. Also calculate rated current of this transformer and the input power
