[0001] The present invention relates to the technical field of high-voltage cable monitoring, and in particular to a monitoring device for a high-voltage cable. Background Art

[0002] High-voltage cables are an important part of the power transmission and distribution system, used to transmit high-voltage electricity from power plants to substations, and from substations to consumers. They are often used to transmit large amounts of electricity to meet industrial, commercial and residential needs. These cables usually include insulation to prevent current leakage and protect the conductors inside the cable. High-voltage cable monitoring refers to the regular inspection and monitoring of high-voltage cables used in power systems to ensure their safe operation and extend their service life.
