    • 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-suppressin line in either an open condition or a closed condition based on at least one of the voltage signal and the current signal.
    • 一种过电压保护系统,包括连接到电气系统的相导体的相位总线和连接到相位总线的一个或多个瞬态抑制线路。 每个瞬态抑制线包括接触器和瞬态抑制元件。 每个瞬态抑制线的接触器由处理器选择性地打开和关闭,从而保护瞬变抑制元件免受过大电流的影响。 还有一种保护至少一个瞬态抑制元件免受过电压条件的方法,包括提供包括与负载并联的至少一个瞬态抑制元件的瞬态抑制线,测量代表一个 瞬态抑制线上的电压和表示瞬态抑制线上的电流的电流信号,以及基于电压信号和电流中的至少一个选择性地将瞬态抑制线路置于开路状态或闭合状态 信号。
