What Is Lightning Arrester


A lightning arrester is a protective device that is used in substations, generating stations, DTR structure, etc to provide protection against surge and lightning strikes. The lightning arresters are composed of ZnO or SiC material. The ZnO or SiC material has the unique property that they don't allow current to pass through them under normal conditions but allows current to through them when a high electric potential is applied.

The lightning arresters provide protection under two conditions, they are

01. Lightning Strikes - Suppose if a lightning tender or strikes occur which has high current, high voltage, and high frequency then this high current flows through arrester then to ground.

02. Surge - When we suddenly isolate the circuit in stations, then surge will occur in lines, these surges are also passed to ground with the help of lightning arresters. The lightning arrester allows surge current to pass through them.

The lightning arresters in substations are always connected at the starting side and also at the end side. The lightning arresters always come first in substations. Well, now I will discuss the types of lightning arresters used.

Why we use lightning arresters? Well, the types of equipment which we are using in substations are costly such as power transformer, current transformer, potential transformer, etc. if lightning strikes fall on these types of equipment, then the equipment may get damaged and the equipment is costly to buy again, so to avoid these things we use lightning arresters in stations.

Types Of Lighting Arresters


01. The value type of lightning arresters
02. Silicon carbide arrester
03. Metal oxide arrester
04. Expulsion type lightning arrester
05. Rod arrester
06. Horn gap arrester
07. Multi gap arrester

Applications Of Lightning Arresters


01. It is used in Substations.
02. It is used in Distribution Transformer Stations
03. It is used in Industries
04. It is also used in Generating Stations
05. It is also used in Home and Buildings

Cost Of Lightning Arresters

The cost of lightning arresters which is used in homes is 6,500 rupees. Well, I will provide amazon link just go and buy, hurry up many people are buying, check it - Amazon (Lightning Arrester).

The cost of lightning arresters which is used in substations and distribution stations varies from 10 $ to 300 $ depending upon a rating.

I hope this article may help you all a lot. Thank you for reading.
