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.

after 15 years of experience I feel important to come back to some basics
city lightning
Protection against the destructive lightning effects should be considered globally.
To avoid the fire of a building we will use the “external” lightning protection system such as lightning conductor or meshed cage.
In the same way, we will install Surge Arrester or surge protector (also called SPD, Surge Protective Device) in the Electrical main board to protect sensitive electrical equipment against surges generated by lightning strokes fell close or directly on the building.
15 years of experience in the field of surge protection lead me to write that the technology and understanding of phenomena has evolved. However, further issues have to be clarified … (more…)
