A lightning arrester (or lightning rod) works by providing a low resistance path to earth. This directs a lightning strike down the side of a building instead of it spreading through the electrical system.

yes
How the voltage arrester works?
The voltage arrester works by conducting when there is enough voltage to turn it on. Often, an arrester on a primary distribution circuit has a spark gap to ground, so that lightning strikes are limited in voltage, protecting the circuit. Other types of arresters, such as MOV's, can be used in surge protectors.
