I would like to share a problem I face when I have to install a surge protection device type 1 in high power electrical switchboard. I already asked this question on another blog, and I’m trying to get more feedbacks from electrical engineers.
The situation is very “unconfortable” for me as a quality provider, because if a short-circuit of high value happens, though luckily probability is low, it would mean very serious safety risks …

As everyone knows, surge protection devices or surge protective devices (SPD) protect electrical equipment against overvoltages caused by lightning. That said, it is not always easy to distinguish between the various technologies or know which to choose.
It’s Good to have in mind practical aspects: case of a low voltage switchboard To achieve the effective installation of the surge protection, the surge arrester’s connections to the grid should be as short as possible. Any cable crossed by a lightning impulse current has a significant voltage to be added to the Surge Protection Device (SPD) residual voltage.
