What is Lightning Arrester ?

Question

Accepted Answer

A lightning arrester is a device used to protect electrical systems from the damaging effects of lightning strikes.

It is also known as a surge arrester or lightning diverter.
It is typically installed on power lines, communication lines, and electrical equipment.
The arrester diverts the high voltage of a lightning strike to the ground, protecting the system from damage.
It works by providing a low-resistance path for the lightning current to follow, preventing it from flowing through the protected equipment.
Lightning arresters can be classified into different types based on their voltage rating and application, such as station class, intermediate class, distribution class, and secondary class arresters.
Examples of lightning arresters include metal oxide varistors (MOV), gap-type arresters, and expulsion-type arresters.
