Whatever the application, the key function of an arrester is to prevent damage caused by voltage surges and lightning strikes. Arresters for use in power systems are available from a variety of manufacturers including ABB, Honeywell, Toshiba, Eaton, and Siemens.
These devices are used to defend the power systems by forwarding the high voltage surges in the direction of the ground. And these power systems and over headlines can also be protected by using ground wire or the earthing from the direct strikes of lightning. The lightning arrester diagram is shown below.
ge is much lower in amplitude. In most cases, the lightning surge is reduced to safe levels for insulation and the a ster is ready for the next one. The surge arrester protects the power systems from both the direct and indirect lightning surge by divertin the charge and energy to ground. In the process of diverting, it clamps the surge on th
When it comes to handling capabilities for high voltages, the station class arresters are the best devices for the job. Among all the arrester types, they are the ones who offer the best discharge voltages and have the capability to withstand the highest of faulty currents.
With the evolution of the electric grid concept, engineers understood that new equipment is required for the protection of high-level voltage power devices. Devices like electrolytic arresters came into evolution during the period 20 th century which is appropriate for high power requirements.
The lightning arrester diagram is shown below. The arrangement of these devices can be done on the towers, transmission poles and buildings to give a secure lane to the voltage & discharging current. Here these can be occurred during the strokes of lightning toward the ground to defend the system from the induced problems of lightning.

What is a Surge Arrester: Working Principle and Types
A surge arrester, as the name suggests, is a device that protects other electrical equipment by "arresting" or discharging surge currents brought about by external (e.g. lightning) or internal (switching events) forces. It is also called a surge protection device (acronym: SPD), or less commonly, a voltage surge suppressor (TVSS).

What is Surge Arrester & what are type of surge arresters?
What is a surge arrester? • Surge arresters are devices that help prevent damage to apparatus due to high voltages. The arrester provides a low-impedance path to ground for the current from a lightning strike or transient voltage and then restores to a normal operating conditions. • A surge arrester may be compared to a relief valve on a boiler or hot water heater.
