Lightning Arrester

Definition

A device that protects electrical units from lightning and power surges.

Purpose

Lightning arresters safeguard electrical systems by diverting high-voltage surges caused by lightning strikes or other power disturbances to the ground, preventing damage to equipment and reducing the risk of fire.

Examples of Use

• Power lines: Installed on utility poles to protect the electrical grid from lightning strikes.
• Buildings: Used in commercial and residential buildings to protect electrical systems and sensitive electronics.
• Communication towers: Protecting antennas and transmission equipment from lightning damage.

Related Terms

• Surge Protector: A device that shields electrical appliances from voltage spikes.
• Grounding: A safety mechanism that provides a path for electrical current to the earth.
• Circuit Breaker: An electrical switch designed to protect circuits from overload or short circuit.

Notes

• Regular maintenance and inspection are necessary to ensure the effectiveness of lightning arresters.
• Proper installation, including adequate grounding, is crucial for the device to function correctly.
• Lightning arresters are part of a comprehensive approach to protecting buildings and infrastructure from electrical surges.
