How does a lightning arrester works?

In: Jobs [Edit categories]

Answer:

Actually when there is lightning it directly falls on lightning arr-ester and this lightning arr-ester is connected with ground wire so that it could not damaged the rest system.

Answer

A lightning arrestor is a protective device used to protect high voltage power lines against lightning strikes. The upper end of the lightning arrestor is connected to a line conductor, and the lower end is connected to earth. For normal operating voltages, the lightning arrestor acts as an insulator, but when a particular voltage is reached due to a lightning strike, the device conducts, providing a path to earth.
