Lightning Arrester vs Surge Arrester: Key Differences, Applications and Selection Guide
A building or an industrial plant stays safe even during powerful lightning strikes or sudden voltage spikes. But how? Lightning arresters and surge arresters provide this protection. But many people assume both as the same thing. They both protect electrical systems, right? Well, not exactly. Are you confused? This blog will discuss how the devices respond differently to different threats and help you decide which one you need. Let’s explore. 1. Lightning arresters protect against direct lightning strikes. Surge arresters protect against internal surges. This is the easiest and the biggest difference to remember. A lightning arrester: Crafted to divert high voltage and current coming from a direct lightning event. It acts as a shield, protecting the building's electrical system from lightning energy. A surge arrester: Deals with sudden voltage spikes that come from switching operations, transformer issues, or indirect lightning influence. The...
