Impact of switching transient in medium voltage capacitor bank.

This paper aims to demonstrate the impact on the insulation of a medium voltage Capacitor bank in the event of a VCU Opening and its effective mitigation measures by implementing surge protection devices, Impact is created due to chopping off the current during the contactor opening, and this chopping current eventually leads to switching transient overvoltage which weakens the insulation level of capacitor units in the capacitor bank.
