ESE Lightning Arrester

A lightning arrester, also known as a surge arrester or lightning rod, is a protective device designed to safeguard electrical systems and structures from the destructive effects of lightning strikes. It works by diverting the massive electrical surge produced by a lightning bolt away from sensitive equipment and structures, such as buildings, power lines, or electronic devices. A lightning arrester typically consists of a metal rod or conductor that is securely installed at the highest point of a structure or connected to power lines. When a lightning bolt approaches, the arrester provides a path of least resistance for the electrical discharge, allowing the lightning current to flow harmlessly into the ground. This prevents the lightning from following potentially destructive paths through electrical circuits, preventing damage, fires, or equipment failure that could result from the high voltage surge.
