A 69 kV, 30 MVAR, three phase capacitor bank is connected in Y with the neutral grounded. It is supplied from source which also has a grounded neutral. The reactance of the source is 0.12 pu on a 10 MVA base. The capacitance of the supply bus is 4 nF. The capacitor bank has capacitance of 16.7 F. The capacitor bank is switched off when the bus is at its rated voltage of 69 kV. What transient frequency is observed on supply bus immediately following this operation? What is the magnitude of this disturbance? Time 12 ms after interrupting the current, one phase of the switch reignites. What is the magnitude of this re-ignition current? If the switch interrupts the re-ignition current at its first current zero, what voltage will be left trapped on capacitor bank
