The biggest mistakes: Pull the plug during thunderstorms

Outside, it thunders and thunders. Do you always think of the old advice that you should pull out the plug in a thunderstorm in all electrical appliances? Read here if this tip is still up to date.

Lightning is and remains an elemental force

If we sit in the warm, while it rains and storms outside, then some of this spectacle can certainly make something comfortable. But when it flashes outside, it hides behind it the huge current of 20,000 amperes. That's why the warnings about thunderstorms are to be taken seriously. Flashes cause millions of dollars worth of damage every year, repeatedly destroying electrical appliances.

Does the lightning conductor provide protection?

The lightning rod was invented back in the 18th century, but even today, not every house is equipped with it. Lightning rods are neither legally nor technically prescribed, so you should first find out if your house owns one before you rely on it.

In addition, lightning rods have unintentionally received company on the roof, such as satellite dishes and solar panels that can attract lightning. And inside the house there is also a problem, because here long metal pipes run through the walls. When a lightning strikes a house, it can happen at enormous currents that so-called secondary currents can flow through the power lines, which may then be dangerous to your electrical appliances.

How to protect technical devices without pulling the plug

To protect against such secondary currents, there are overvoltage protection devices. These are divided into categories of 1 to 3 in strength. Devices of type 1 sit z. B. at the points of the building, where lines lead from outside to inside. These are still too weak to protect the electrical appliances themselves. Only Type 3 protects your devices. Such a protection is partly installed in electrical appliances themselves and in addition there are surge sockets.

The solution: power strip with surge protection

So it is true that electrical appliances must be disconnected from the mains during thunderstorms. But if you want to save yourself the annoying plug pulling, you can also simply use power strips with surge protection. These protect your devices and the manufacturers provide you with additional insurance coverage. If your devices and lines are not protected by overvoltage protection devices, only one thing remains in case of a thunderstorm: Pull the plug!
