What happens to a lightning arrestor after a lightning event?

After a lightning event, a lightning arrestor may sustain damage due to the high voltage and current associated with lightning strikes. While some models are designed to absorb and redirect the energy from a lightning strike, they can become degraded or fail as a result of exposure to such extreme conditions. Therefore, it is often necessary to inspect the arrestor after a lightning event to assess its condition and determine if it needs to be replaced to ensure continued protection for the electrical system.

Lightning arrestors are built to protect electrical equipment, but they have limits. If a lightning strike exceeds these limits, the arrestor may become compromised, resulting in reduced effectiveness or total failure. Regular maintenance and checks following storm events are essential to ensure that these protective devices are operational when needed most.
