Back Fill Compound-Significant for Earthing Systems - By: Jimmy Seikh

Why Earthing is essential?
The importance of earthing in electrical networks is for the safety of the lives around it. When all the open wires of an electrical network is grounded than even if there is some problem in the insulation the extra voltages passes to the ground and no voltage is left in the circuit board and no one will cause any harm because of short circuiting. The electronic appliances are saved from high voltages if they are under any faulty condition. Dissipation path is provided to all the open ends of electrical network. The appliances which require stable voltage earthing is very essential in that case or there are chances that the appliance might halt because of fluctuation in the voltage supply.

Purpose of Earthing Electrodes
Earthing electrodes is a kind of rod which you will find at the end of a building. It is required because when lightning is taking place it should provide static electricity. The rod is basically connected to the grid from where other points get power supply. The standards for installation vary according to the country. The size of the grid is equivalent to the perimeter of the building. Back Fill Compound is used along with earthing electrodes to absorb moisture because these all components are installed beneath the ground. BFC has the capacity to absorb moisture up to thirteen times its actual dry volume. It does not let moisture cause any inconvenience in the conduction of power.

What is lightning arrester?

The purpose of lightning arrester is to save the insulation of any electrical system. It is also known as surge which has very high voltage terminals and a terminal for ground. When lightning strikes the surges move towards the power system and reaches the arrester there these surges are redirected towards the insulated area and commonly to earth. There is kind of arrester called as ese lightning arrester which has discharge capacity up to 100% and provides protection of very high level. The durability of these rods is also for longer period of time. The best feature of it is that it does not require any external or additional power supply. It works well irrespective to any climatic condition.

It is a necessary thing to have general information regarding the electrical components and the functionalities. This can help in case of emergency situations. A regular check of your own electrical appliances and the electrical circuit is a good action and this will ensure safety of your loved ones living in the house.
