Fault detection of high voltage transmission lines and distribution systems is a challenge for insulation maintenance personnel. The main problem is the corona phenomenon, with air molecules around the conductor being charged or ionized to produce a corona discharge. Energy loss during the operation of replacing the high voltage transmission line and deterioration and degradation of the insulator to eventual failure are two major concerns for maintenance personnel.

When the electric field strength ionizes air molecules around the insulator, chemical reactions can occur, corroding metal parts and weakening the ability of the insulating compound. The high energy produced by the corona discharge will cause severe damage to mechanical components, causing unexpected outages and loss of service to thousands of customers, which can lead to fire and explosion phenomena. Fires and explosions in factories caused by electrical causes will generate serious chain reactions depending on the status of dangerous and toxic chemicals on their site.
