The following diagram represents one phase of a 3-phase, \( 69 \mathrm{kV} \) circuit, containing a source and a capacitor bank \( C \), which is rated at \( 15 \mathrm{MVA} / \) phase. \( L=60 \mu \mathrm{H} \). Calculate: a) The peak voltage that can be attained by \( C \) when the switch is closed and \( C \) has been fully discharged, assuming that the closing takes place at the peak of the supply voltage b) The time it will take for \( \mathrm{C} \) to reach this voltage c) The peak current during the operation d) The steady state rms current passing through the switch after the transient has subsided, since any practical circuit would contain some damping.
