A 100 kVA, 50 Hz, 230/50 kV testing transformer has an 8% leakage reactance and a 2% winding resistance. A cable of capacitance 15 nF is to be tested at 250 kV using this transformer as part of the resonance circuit. Determine the value of the inductance (Q-factor = 20) required to obtain resonance and the value of the input voltage required. (Q-factor = XL/r )

Question

A 100 kVA, 50 Hz, 230/50 kV testing transformer has an 8% leakage reactance and a 2%
winding resistance. A cable of capacitance 15 nF is to be tested at 250 kV using this transformer
as part of the resonance circuit. Determine the value of the inductance (Q-factor = 20) required
to obtain resonance and the value of the input voltage required. (Q-factor = XL/r )
