  • Surge Arresters


Arresters are intended to limit the adverse effects of disturbances in electrical transmission systems that take the form of high voltages. Two sources of such high voltages are atmospheric lightning and internal disturbances originating in the line itself. Although arresters are designed to take care of atmospheric lightning and those internal surges that are transient in nature, they generally are not designed to be operated under continuous surges. It is advisable to locate arresters, especially if oil-filled, outdoors wherever practicable. Appropriate ground connections are absolutely required for satisfactory operation of arresters. Arresters should be treated the same as other live parts of equal voltage for guarding purposes, and their special problems should also be recognized. Live parts in the vicinity of arresters can be satisfactorily protected by location from the action of arresters and associated equipment.
