In order for the Surge Protection Devices (Surge Arresters) devices to operate smoothly, there must be a grounding system with a surge arrester correctly selected according to the protection zone and the line to be protected and potential equalization point / points established within the framework of valid standards.

Second Stage: Type 2 / Class 2 / C Class Surge Protection Devices (Surge Arresters) are circuit elements used in the secondary and / or lower secondary panels of the facility / building. Compared to Type 1 / Class II surge arresters, their strength is lower but their sensitivity is better.

Some models have contacts that are active when malfunctioning and / or indicators that indicate malfunction by changing colors.

It should have been tested in an 8/20 µSec waveform. It must be able to discharge a load of at least 10kA between Phase-Neutral, and at least 25kA between Phase, Neutral-Earth.

While Yıldırım poses a clear threat to a building / facility, it is also a growing threat for these systems due to the increasing use of electrical and electronic equipment inside.

In this context, EN / IEC 62305 standard handled the issue of Lightning Protection as a whole and offered solutions to prevent all risks. Accordingly, a correct application project supported by external and internal lightning systems for protection from lightning will provide a cost-effective protection to minimize loss of life, property and time.
