How to protect equipment from voltage surges

[batasakas]

Sudden voltage drops pose a threat to all household appliances. In the worst case, the devices will simply burn out: they will not even be repaired. Why do voltage drops occur and how are they dangerous for equipment? How to reliably protect yourself from voltage surges? Details are in our material.



How dangerous are voltage surges?
There are many reasons for a sharp voltage surge. An accident in the power grid, a substation overload, the simultaneous shutdown of several powerful devices - all this can lead to surges. Another common cause is a lightning strike on a power line or... a missile hitting an energy facility.

In everyday life, small voltage drops are a normal germany number data phenomenon. Equipment manufacturers provide a margin of 10%. A voltage jump of up to 240 V usually does not pose any danger. There are few exceptions: for example, some measuring devices have a lower permissible deviation threshold. However, regularity is important here. Too frequent voltage drops threaten with failures in control units, loss of settings, and so on.

Voltage drops in an apartment can be detected by indirect signs:

too frequent burning of light bulbs;
periodic change in light intensity in lighting devices;
unstable operation of equipment.
Any surge that raises the voltage in the network above 240 volts is harmful to home appliances. Drops of 10-25% reduce the service life of devices by almost half. They can lead to breakage. A voltage surge of up to 300 volts disables power supplies, control and touch panels, electric motors, and network equipment.

How to be safe? First of all, you should pay attention to the wiring. Low-quality wiring may not withstand heavy loads. In the worst case, everything will end in a short circuit. There are various devices to protect equipment - we will tell you about them in more detail.

Voltage relay
The simplest and most affordable device. The relay performs only one function - it opens the circuit when the input voltage exceeds the specified limits. The upper and lower limits, as well as the turn-on delay time, can be set independently.
