description The invention relates to the technical field of alternating-current looped network detection, in particular to an alternating-current looped network fault searching method and device. The method comprises a phase line grounding and looped network troubleshooting stage of a feeder loop and a zero line grounding and abnormal looped network troubleshooting stage of the feeder loop. Phase line multipoint grounding, phase line looped network, zero line multipoint grounding and abnormal zero line looped network faults are intelligently checked through magnetic induction and electromagnetic coupling. According to the device, the host and the handheld tester adopt a satellite communication technology, real-time data interaction is realized, the accuracy of operational data is ensured, and the anti-interference capability is high. The device adopts the design concept of one machine with multiple functions, the main machine can complete the main functions of coupling injection of characteristic signals, high-frequency
