Lightning Protection Methods:
Lightning is a high-voltage natural phenomenon that can cause severe damage to power systems. It occurs due to the discharge of electrical energy between clouds or between clouds and the ground. In power systems, lightning can lead to overvoltages, insulation breakdown, equipment damage, and power outages.
Lightning protection schemes are designed to prevent damage to electrical power systems caused by direct or indirect lightning strikes. Some of the lightning protection methods are:
- Overhead ground wires: Used to shield transmission lines from direct lightning strikes.
- Earthing screen: Protects substations by providing a grounded metal mesh to dissipate lightning energy.
- Lightning arrestor: Directs high-voltage lightning surges safely to the ground.
