If the incoming line is shielded, there needs to be a backflash not too many spans from the substation to a phase conductor for the surge to pose a problem. When a backflash occurs at a tower, it produces a fast rising surge. But as...See more on inmr

Protecting substations from lightning and switching surges that lead to insulation flashover has been a key issue for as long as there have been power systems. While this need has remained constant over 100+ years, options on how best to mitigate high voltage stresses have changed quite substantially.
Learn about essential lightning protection measures for substations and transformers, including the use of lightning rods, surge arresters, and protective gaps on both high-voltage and low-voltage sides to ensure reliable electrical system performance.
Example of substation with line entrance arresters, primary arresters, secondary arresters and OHGW protection. Considerations in the protection of substations are listed and covered below showing different performance criteria: Failure Rate This is the acceptable number of insulation failures over the service life of the station.
This measure ensures balanced protection across all terminals and prevents asymmetric voltage stresses from damaging the transformer core or secondary windings. A substation without adequate lightning protection is akin to a fortress without walls.
