What is the reason for the thunder and power failure?

When it thunders, the power is cut off because the lightning is too strong, and the generated powerful electric energy meets the setting values of series protection relays and protection circuit breakers in UHV, high-voltage and low-voltage power grids. These protection devices must trip at this time to ensure the safety of power facilities and the personal safety of users connected to the power grid. Because the whole power generation, transmission and distribution of the State Grid is a complete system, with a vast territory, long transmission lines and wide distribution, and being located in the wilderness, it is easy to be struck by lightning, and it is normal for lightning to cause tripping and power failure accidents.

Matters needing attention

When it thunders and rains, it is forbidden to stay at the top of the mountain or in hilly areas. More importantly, it is forbidden to continue to push the rain to the heights. You shouldn't hide under a big tree or near a telephone pole, nor should you walk or stand in an open field. You should hide in a low-lying place as soon as possible, or try to find a house or a dry cave to hide.

In thunderstorm weather, don't use an umbrella with a metal handle. Take off glasses, watches and belts with metal frames. If you travel by bike, you should leave the bike as soon as possible and stay away from other metal objects to avoid being struck by lightning.

Don't go swimming, boating and fishing in rivers and lakes in thunderstorm weather.

When it is thunderous and stormy, visitors should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid using electricity if they rest in the hotel. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.
