不良碍子を迅速に発見することは不可能であった。(Prior art) Insulators that insulate and support power transmission lines are made of durable and stable porcelain, but because they are installed and used in harsh environments for long periods of time, Deterioration may occur due to shock, etc. Conventionally, in order to detect such deteriorated insulators, it was common for a worker to climb a steel tower and inspect each insulator for insulation deterioration using a defective insulator detector attached to the tip of an insulating rod. However, this conventional method has the disadvantage of being dangerous and unsafe because it requires operating a long insulating rod on the steel tower to bring the defective insulator detector into contact with the live insulator. . In addition, such conventional methods have poor work efficiency because they require climbing up each steel tower, and it is impossible to quickly discover defective insulators in the event of an accident.
