Why is the phenomenon of thunder in formation?
Thunder or lightning is a phenomenon that occurs when clouds carrying left-hand charged electricity touch and release electricity in the atmosphere. They have a speed of up to 36,000km/s. Lightning only appears during thunderstorms.
According to experts, in Vietnam, the first rains of the season will be accompanied by a very dangerous phenomenon of lightning. In addition, thunder is not distributed evenly by country or region.
About 70% of heavy rains and thunderstorms occur in the tropics, especially in areas with high air convection. Including Vietnam, it is estimated that our country is hit by about 2 million lightning storms every year, mainly in areas such as Hai Duong, Ha Tinh and the Mekong Delta.
How to prevent thunderstorms for families during the rainy and stormy season
Application when there is thunderstorms
When there is thunderstorms, you should limit going out as much as possible, preferably indoors. Do not take shelter from the rain in warehouses, bus shelters or high trees or embankments. In addition, you should not hold metal tools such as knives, markers, etc. and do not stand near large animals.
Domestic appliances such as refrigerators, TVs, air conditioners, wifi networks, etc. must withdraw all sources. When inside the house, you should stay away from doors, windows, and electrical appliances, avoid damp places such as water tanks and shower pipes, and do not use your phone unless necessary.
Installing towing posts on the roof
This is one of the methods of avoiding lightning strikes in many high-rise buildings today. This method is both cheap and easy to implement.
The towing column operates according to the principle that when lightning hits the roof, the towing column will transmit electricity to the ground. Therefore, the towing columns are often made of metal, sharp and in high position.
Use a lightning-proof socket
anti-lightning propagation is a new device in recent years, it will keep electrical appliances in the home safe when hit by lightning.
Many outlets integrate technology to connect to Wifi and just need to connect to the phone to be able to adjust the power off and off whenever necessary. They are also easy to buy on the market and affordable.
Control the house with a tongue
This solution seems new but works very effectively. The fuse fuse has a simple structure, a large range of application and protects the entire building and the internal power line system.
They operate according to the principle of accumulating electricity and releasing it through the optical disc port. The cost of installing lightning protection with a watch brand is also cheap and is applied by many families in rural areas.
