A device that is used in telecommunications systems and electrical power systems is known as a lightning arrester which is used to safeguard the conductors and the insulation of the system from the damage caused by lightning. A characteristic lightning arrester consists of a ground terminal and a high voltage terminal. As a switching surge or lightning surge both are very similar passes to the arrester along the power line, the current that comes from the surge gets diverted via the arrestor in almost all instances to earth. Hence in the case of severe light also it can pass the current to earth that can help the unit save from the devastation.

How does it work?

In cases of telephony and telegraphy at the place where wires go into the structure is positioned a lightning arrestor which prevents harm to electronic instruments inside and makes sure the safety of people who are near them. You find minor versions of lightning arresters which are also known as surge protectors are tools which are linked to every electrical conductor in communications and power systems and also to the earth. By use of them, signal currents and flow of the normal power is prevented from flowing to the ground. On the other hand, it facilitates the passageway over which flows high voltage lightning current that bypasses the connected kit and equipment. They are used to limit the rise in voltage whenever a power or communication line gets struck by lightning or happens to be close to a lightning strike.

If it happens that there is no protection or it fails, the electrical system gets struck by lightning which introduces thousands of kilovolts that may surely destroy the transmission lines. It can impose severe damage to electronic or electrical devices and to transformers. As a fact, intense voltage spikes lightning produced in incoming power lines can destroy electrical home appliances or in some cases can even cause death.

The system:

A target that is vulnerable to a lightning strike, for example, a television antenna is linked to the terminal one, and the terminal two is connected to a long rod that you then bury it in the ground. Normally there is no flow of current between the ground and the antenna, and there is found high resistance. In a lightninssssg strike, the voltage is many times more or higher than that is usually required to make electrons move via the two air gaps. As a result, the electrons move via the lightning arrester and do not take the path to a television set which does not get destroyed in the process.

The caps and coverings are mechanical shear head lugs and connectors. It is used to keep the electrical appliances and equipments protected in your homes as it handles the high voltage spikes. They can be used in a number of conducting applications either small or large. They are normally fashioned out of an alloy of brass and aluminum and are able to tackle the excess voltage spikes up to 42KV.
