    摘要: An over-voltage protection system including a phase bus connected to a phase conductor of an electrical system and one or more transient-suppressing lines connected to the phase bus. Each of the transient-suppressing lines includes a contactor and a transient-suppressing element. The contactor of each transient-suppressing line is selectively opened and closed by a processor, thereby protecting the transient suppressing element from excessive currents. Also a method of protecting at least one transient-suppressing element from over-voltage conditions including providing a transient-suppressing line including the at least one transient-suppressing element in parallel with a load, measuring at least one of a voltage signal representative of a voltage on the transient-suppressing line and a current signal representative of a current on the transient suppressing line, and selectively placing the transient-suppressing line in either an open condition or a closed condition based on at least one of the voltage signal and the current signal.
