ンスボンド。[Claims for Utility Model Registration] On the primary side, the train currents I 1 and I 2 flow respectively,
It consists of lower coils 4, 6, and a secondary coil 5 disposed between the upper and lower coils 4, 6 through which a signal current flows. The extension parts 4b and 6b are each rail R1
, R 2 , is passed through the mutually parallel portions of the extensions 4b and 6b, and is excited by the AC operating voltage E to cause magnetic velocity in the opposite direction. The DC-CT 15 is equipped with first and second magnetic cores 20 and 21 which have come to generate an alternating current due to impedance reduction of the magnetic cores 20 and 21 that occurs when the absolute values of the train currents I 1 and I 2 are not equal. An impedance bond characterized by comprising a rectifier circuit 24 that rectifies an output, and a detection circuit 25 that detects the presence or absence of an unbalanced current depending on whether the output from the rectifier circuit 24 is above a predetermined level.
