It shows the components of the circuit as simplified shapes, and the capacity and signal connections along with the devices. The plug-in arrestors are completely replaceable and supplied as spares unit when they have worn out. Working Principle. Radius of protection certified and specific . polymer distribution/riser pole arrester is designed to limit surge voltage by conducting the surge current to ground, and thus avoiding equipment damage. Sample Drawings. Lightning arrester is a device that allows lightning current to flow into the ground so that electrical equipment does not generate high voltage. It shows the components of the circuit as simplified shapes, and the knack and signal friends together with the devices. The function of the surge arrester is to allow the discharge of any dangerous over-voltage before it can do damage and then to restore the line to normal operation after the discharge. Figure 4. The arrester is of single pole design, suitable for outdoor use, and designed in accordance with the latest revision of the ANSlllEEE C62. Earthing System.
