The current detector unit 17 having the through-hole of the primary conductor of the three-phase circuit and the image current detector unit 18 are integrally combined, and the through-holes 20 and 21 are concentric with each other. Preferably, three through holes are arranged at the positions of the respective vertices of the triangular shape, and the primary conductors are arranged in the holes. The current outputs from the current transformer windings 8, 9, and 10 are converted into voltage signals by a resistor 27 circuit connected in parallel via a full-wave rectifier circuit 11, and the terminal 23 Is output from The resistor 27 is connected to the output of the full-wave rectifying circuit 11 in any combination by the switch 22.
