Lightning arrestors and surge protectors are both essential devices used to safeguard electrical and electronic equipment from voltage spikes and surges, but they serve different purposes and offer distinct levels of protection.
Lightning Arrestors
Lightning arrestors, also known as lightning rods or lightning conductors, are primarily designed to protect buildings and structures from direct lightning strikes.
They work by providing a safe path for lightning’s electrical energy to follow, diverting it away from the structure and into the ground.
This prevents lightning from causing damage to the building’s electrical and structural systems. Lightning arrestors are typically installed on the highest points of buildings and are often connected to grounding systems to disperse the electrical energy harmlessly into the ground.
While they can help protect against lightning-related damage, they may not offer comprehensive protection against all types of electrical surges and spikes.
Surge Protectors
Surge protectors, on the other hand, are designed to protect sensitive electrical and electronic devices connected to them from voltage spikes and transient surges.
These surges can be caused by various factors, including lightning strikes in the vicinity, power grid fluctuations, or electrical faults. Surge protectors act as a barrier between the incoming power supply and the connected equipment.
They detect voltage spikes and divert excess energy safely to the ground, preventing it from reaching and damaging the devices. Surge protectors are commonly used for computers, home entertainment systems, appliances, and other valuable electronics.

In summary
The main difference between lightning arrestors and surge protectors lies in their primary function and scope of protection. Lightning arrestors are focused on safeguarding structures from direct lightning strikes, while surge protectors are designed to shield electronic equipment from voltage spikes and surges.
