In thunderstorm weather, why should the substation attendant wear insulating boots when conducting outdoor patrol?

Substations are generally equipped with several high lightning rods, and the grounding downlead of the lightning rod is connected with the surrounding grounding electrode. In thunderstorm weather, lightning strikes the lightning rod, and a potential distribution area is formed around the grounding electrode of the lightning rod in a large range, and its potential is generally very high.

At this time, when the personnel on duty in the substation conduct outdoor patrol, there will be a high step voltage between their feet, which may lead to an electric shock accident. Therefore, the Electrical Safety Work Regulations clearly stipulates that insulating boots should be worn when patrolling outdoor high-voltage equipment in thunderstorm weather, and lightning arresters and lightning rods should not be near.
