A 6 MVar capacitor bank is connected to a 13.8kV bus shown below. The equivalent impedance, as seen from the 13.8kV bus is, Z = 0.0115 j 0.1056 pu on a 100 MVA base. Derive an equation modeling the inrush current transient when the Circuit Breaker CB1 is closed. Calculate value of the peak inrush current and voltage if the capacitor has no initial charge. Also determine the frequency of this transient. Question 2: The scenario in Question 1 is modified by adding another 6 MVAr capacitor on the 13.8kV bus. Assume CB1 was closed for a long time and Bank C2 is energized by closing Circuit Breaker CB2. Determine peak value of the current transient and its frequency
