In this article, we will try to discuss the outlook of lightning protection inside the premises of an electrical substation… Enjoy and please comment below!

Lightning protection Introduction in context to part one

Lightning strikes are a natural phenomenon and high power surges regularly hit the vulnerable parts of earth’s crust. Electrical installations including the transmission lines and sub stations are quite vulnerable for lightning to strike due to the following reasons;

Check the great article we received in our boxmail. It’s about Electrical protection and it tells you which are the 4 fundamental qualities every power protection system should possess. Enjoy!

In power generating stations, all most all electrical circuits and equipment tend to generate faults. This is generally caused due to insulation fail between conductors and ground, or due to fail of insulation between the various conductors themselves.

4 qualities every power protection system should possess 1

Though the reasons for an insulation fail keep varying, the result is the same, “excess flow of current.” When excess current flows through weak resistances, the inrush current can severely damage the electrical equipment, resulting in extensive operational loses.
