Type 1 + 2 / Class 1 + 2 / B + C Class compact protection elements have been used as second level protection in recent years.
It should have been tested in 10/350 µSec waveform. It must be able to discharge a load of at least 40kA between Phase-Neutral, and at least 100kA between Phase, Neutral-Earth.
It is used in the electrical panel of the uninterruptible power supply and / or in the secondary panels positioned like a main panel.
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.
