In terms of safety, lightning arrestors are primarily designed to protect which of the following?

Lightning arrestors are devices specifically designed to protect electrical equipment from lightning strikes. Their primary function is to divert the high voltage generated by a lightning strike away from sensitive electrical components, thereby preventing damage to transformers, circuit breakers, and other critical devices found within substations and electrical installations. This protection is crucial, as lightning strikes can result in significant disruptions and costly repairs.

While buildings, vehicles, and people may also be at risk during a lightning event, the primary purpose of lightning arrestors is focused on safeguarding electrical infrastructure. Properly functioning lightning arrestors help maintain system integrity and reliability by ensuring that electrical equipment remains undamaged during electrical surges caused by lightning.
