    • In one aspect, the invention provides a residual current device (RCD) for protecting a circuit by tripping in response to an imbalance signal representative of residual current imbalance in the circuit. The RCD trips the circuit when the imbalance signal exceeds a predetermined threshold rating. The RCD comprises test means for increasing the imbalance signal so as to test operation of the RCD against the rating. In another aspect the RCD comprises: a current transformer for generating an imbalance sense current in a sense coil in response to a current imbalance in an electrical supply; and a degaussing coil for substantially removing remanence in the current transformer by application of a degaussing signal to the degaussing coil.
    • 一方面,本发明提供一种用于响应于表示电路中的剩余电流不平衡的不平衡信号而跳闸来保护电路的剩余电流装置(RCD)。 当不平衡信号超过预定阈值额定值时,RCD跳闸电路。 RCD包括用于增加不平衡信号的测试装置,以便根据额定值测试RCD的操作。 在另一方面,RCD包括:电流互感器,用于响应于电源中的电流不平衡而在感测线圈中产生不平衡感测电流; 以及消磁线圈,用于通过向消磁线圈施加消磁信号来基本上去除电流互感器中的剩磁。
