What is a Lightning Arrestor?
Introduction
A lightning arrestor is a device used in electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrestor has a high-voltage terminal and a ground terminal.

Function of Lightning Arrestors
- Protection: Provides a path to ground for high voltage surges, typically caused by lightning, thus protecting the electrical systems from damage.
- Insulation Safety: Helps in maintaining the integrity of insulation by diverting the lightning surge to the ground.
- Voltage Control: Controls the voltage level within the system by providing a low impedance path to ground.
