Protecţie la supratensiuni

A surge is a voltage spike - a level of voltage in an electro-energetic network that is higher than the denominational voltage or higher than the allowed deviations. There are several factors that can cause surges to occur.

The surges that may be dangerous for appliances or people are primarily temporary. Temporary surges occur as relatively short-term changes in voltage between two stationary conditions. The reason for such surges to occur can be found in lightning strokes, electromagnetic fields generated by such lightning strokes or switch manipulations.

With the correct use of surge protection elements or a correctly used combination of the same, the effective surge protection is possible. In other words, following the necessary precautions, the appliances connected to the electric network will not sustain damage in case a surge occurs.

The correct use of surge protection elements depends primarily on the electro-energetic system and on the level of protection the customer aims to achieve.
