<P>PROBLEM TO BE SOLVED: To provide a current sensor with an electric leakage detection function, which is capable of detecting current values of a leakage current and a current in each phase flowing in a two-way electric wire by one sensor (core), in a state of the two-way electric wire without dividing an electric wire. <P>SOLUTION: The current sensor with an electric leakage detection function includes: electric circuit conductors 11a and 11b as a plurality of primary conductors spaced from each other by a prescribed gap; a magnetic substance core 12 circling the plurality of electric circuit conductors 11a and 11b; an electric leakage detection coil comprising a toroidal first coil 23 having a winding wound around the magnetic substance core 12; and a current detection coil comprising a toroidal second coil 13 circling a partial peripheral area r1 of the magnetic substance core 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
