Lightning Arrester- A Protective Device

Lightning, one of the natural disasters, has been proved highly devastating. To counteract its effect, today telecommunication and electric supply companies are resorting to Lightning Arrester. This device is responsible for the protection of conductors and insulator systems installed in the telecommunication and electric supply systems from the devastating lightning effects. Lightning Arrester nullifies the effects of current coming towards it.

Lighting Arrester, which is also known as surge protectors or arresters, is installed on electrical service panels. This device consists of two terminals- high voltage terminal and ground terminal. It prohibits the flow of current towards the Earth and lays down a new path for its flow. When the high voltage lightning hinders the working of power and communication systems, Lightning Arrester prevents the rise in voltage. There is a wide range of Lightning Arresters, namely, Gel Earthing, Earthing Electrodes and Earth rods. Every electricity supply system is incomplete without Earthing System. Earthing system completes the whole circuit and protects you from the shock. The Earthing System is revered in all kinds of Lightning Arresters. It is usually made from copper or brass and has a wide range of application for residential and industrial purpose. The base of gel earthing is chemical and alloys of metals. It is composed of a crystalline mixture which acts as a conductor. It indulges in protection of main Earth i.e. soil. Earthing electrodes are connected to the central point of power supply to the whole building. These are able to generate static current whenever lightning comes into action. Now and then, moisture creates problem in the power conduction. To get rid of this problem, Earthing Electrodes are installed along with Back Fill Compound. Since Electrodes are installed beneath the ground hence are constantly exposed to moisture. Back Fill Compound also protects the equipment from any kind of fluctuation and looks after the consistent current value.

The National Fire Protection Association incorporates all the information about lightning arresters; hence it can be referred in case of any doubts related to usage or installation of arresters.

Earthing System is the best to opt for, if the protection is the main concern. Never think of an electricity supply system at the cost of the life.
