    • An automated AC line filter and surge suppression apparatus (100) having an inductive current sense loop (ICSL) circuit (10) for sensing inductive current at a load and controlling the application of AC line filter (112) to an AC power line to the load. Current sensor (12) in series with the input line senses inductive load current. A first bridge rectifier (14) rectifies the sensed load current to a proportionate DC voltage, which triggers a switch (24). The output of switch (24) is fed into an opto-isolator (26), which in turn controls second switch (28). Switch (28) connects or disconnects AC line filter (112) from the system according to a predetermined sensed inductive current at the load. MOVs (102) and capacitive elements (104) provide continuous surge suppression protection to the load. Selectable biasing (255) provides line filtering corresponding with a phase difference in inductive load current and a load voltage.
    • 一种自动交流线路滤波器和浪涌抑制装置(100),具有感应电流检测回路(ICSL)电路(10),用于检测负载处的感应电流,并控制将AC线路滤波器(112)应用于AC电力线 加载。 与输入线串联的电流传感器(12)感应感性负载电流。 第一桥式整流器(14)将感测到的负载电流整流到比例直流电压,其触发开关(24)。 开关(24)的输出被馈送到光隔离器(26),光隔离器又控制第二开关(28)。 交换机(28)根据负载处的预定感测电感电流将交流线路滤波器(112)与系统连接或断开。 MOV(102)和电容元件(104)为负载提供持续的浪涌抑制保护。 可选偏置(255)提供对应于感性负载电流和负载电压相位差的线路滤波。
