Abstract
It is disclosed a technique in which Controlled Switching Devices (CSDs) are used to control medium and high voltage circuit breakers to mitigate switching transients. This invention describes a method for controlling the closing of a circuit breaker to mitigate and/or eliminate the inrush current in capacitive loads such as capacitor banks and filters by taking into account the residual DC voltage charges that may be present in the load. It is disclosed a method to perform fast switching operations on capacitive loads and therefore eliminate the load discharge period.
