摘要： A test plug for use with protective relays has a circuit that when it detects an overvoltage on the secondary side of a current transformer limits the overvoltage amplitude and the occurrence of the overvoltage to a predetermined number of peaks that are less than all of the peaks that occur when the secondary side is open circuited and the test plug is connected to the relays. The test plug also ensures that there is a continuous flow of current in the relays. The test plug further that has an indicator visible external to the plug to indicate the occurrence of an open circuit transformer secondary and that indicator remains illuminated when the test plug is disconnected from the protective relays.
摘要翻译：与保护继电器一起使用的测试插头具有一个电路，当它检测到电流互感器的次级侧的过电压时，将过电压振幅和过电压的发生限制到预定数量的峰值，其小于所有峰值，当次级侧断开并且测试插头连接到继电器时发生。测试插头还确保继电器中持续的电流流动。测试插头还具有在插头外部可见的指示器，以指示开路变压器次级的发生，并且当测试插头与保护继电器断开时，该指示器保持点亮。
