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. In the graphic below, a Surge Protection Device (Surge Arrester) principle diagram and Stepped Damping Chart are given with the correct project. First Stage: Type 1 / Class 1 / B Class lightning protection surge arresters are the front protection units of the facility / structure. They are circuit elements capable of absorbing and damping direct lightning strikes that may come from power lines. It must be installed in the main distribution / transformer panel inside and / or outside the building. It should have been tested in 10/350 µSec waveform. It must be able to discharge a load of at least 50kA between Phase-Neutral, and at least 100kA 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.
