Q5/ A 6.6 kV/350 kV, 350 kVA, 50 Hz testing transformer when tested had the following observations: (a) No load voltage rise on HV side was 1% more than the rated value when 6.6 kV was applied on primary side. (b) The rated short circuit current was obtained on HV side when shorted with 8% rated voltage on primary side. Calculate (i) self-capacitance of transformer along with its HV side bushing, and (ii) leakage reactance neglecting resistance
