Abstract
A system and method for suppressing a subtransient current and an overvoltage in a power system. A subtransient current is identified at a location in the power system. The subtransient current at the location in the power system is directed to ground for a time delay in response to identifying the subtransient current at the location in the power system. Directing the subtransient current at the location in the power system to ground is ceased in response to identifying an end of the time delay. An overvoltage is identified at the location in the power system. The overvoltage at the location in the power system is suppressed in response to identifying the overvoltage at the location in the power system.
