The utility model provides an on-line detector for a fault indicator. The device comprises a point contact switch, a magnetic conductive iron core capable of triggering a fault indicator to turn over,an exciting coil and an inverter power supply, the anode of the inverter power supply is connected with the point contact switch through a wire; the cathode of the inverter power supply is connectedwith the exciting coil through a wire; the exciting coil is wound on a magnetic conductive iron core capable of triggering the fault indicator to turn over; beneficial effects, fault indicator withoutdisassembly and assembly, a point contact switch button on the surface of the insulating cover touches the surface of the fault indicator; the point contact switch is switched on, the exciting coil loop is switched on, alternating magnetic flux generated by the exciting coil acts on the induction coil in the fault indicator through the magnetic conductive iron core, and if the electric quantity of the fault indicator is su
