Development of class 2 and class 3 surge protection devices for low voltage systems

Due to the increased use of sensitive electronics, specifically microelectronics, even modest lightning activity can cause equipment indemnity. Lightning effects can Noccur at all levels of power systems either directly or indirectly, including transmission, generation, and distribution. Therefore,...
