The utility model relates to the technical field of power monitoring system, and discloses a cable grounding remote monitoring system. The system is provided with a zero sequence current transformer which is fixed on a 0.4 kV to 35 kV field branch power distribution cable, and the zero sequence current transformer is connected with a radio transmitter through a small current neutral grounding detection circuit. The radio transmitter is connected with a radio reception controller through an antenna in a wireless manner. An output end of the radio reception controller is connected with an audible and visual alarm. The radio reception controller is connected with distribution network automation through a modem. The system can reduce check-up connection processing and grounding operation time for circuit administrators, reduces workload, relieves two-phase devices from being damaged by line voltage when grounding, improves device service life, and reduces resonance time of the current transformer, the transformer, and a ferromagnet. A most important point is to reduce life safety risks of live check-up connection personnel and personnel around a grounding point. The system is large in adaptable voltage range, low in cost, easy in implement and resource sharing, and distribution network automation level is improved.
