At this time, a telephone pole is installed to supply electricity from a substation to a factory or a house, which is a final consumer, and a power transmission line is installed in a telephone pole to supply electric power.

A high-voltage current flows through the working transmission line attached to the electric pole, and the working transmission line is connected like a mesh.

However, if the insulation of the transmission line is destroyed by the deterioration of electrical equipment such as insulators of a telephone pole that fixes the transmission line connected with such a complicated structure, burning by lightning, contact with trees or algae, If a power failure occurs due to the operation of a switching device such as a protective device, the operation of the industrial equipment is interrupted and the operation of household appliances such as a refrigerator in the home is stopped. In the event of a failure, quick recovery should be done in a short time.

Nonetheless, there is currently no way to find out where the over current is flowing because the insulation is destroyed anywhere on the overhead transmission line, which is widely distributed like a network, It takes a lot of time to find out a specific fault point.
