A lightning arrester is a device system to prevent our electric devices and electric shock from lightning strikes. It works by redirecting the current from a lightning strike to the ground. It has two parts, one is placed on top of the building and the other is buried in the ground. This system is detailed in the AutoCAD line for use in electrical design.
