Earthing provides stability to electronic equipment.

Purpose of earthing an electrical appliance. Earthing is an important component of electrical systems because of the following reasons. It keeps people safe by preventing electric shocks. It prevents damage to electrical appliances and devices by preventing excessive current from running through the circuit.

It prevents the risk of fire that could otherwise be caused by current leakage. To prevent the person form electric shock In case of earthed appliances if there is any leakage of current or the live wire comes in contact with its body then the current flows to the ground through earth wire. Aug 10 2008 0154 IST As its a safety factor earthing is essential and mandatory.

Its an electrical connection between the exposed metallic parts of an electrical appliance or installation and the earth regarded to have zero potential. Proper earthing provides an alternative and easy path for leakage or faulty current to flow. What is the Purpose of an Electrical Earth Earthing Definition.

Connecting the metallic body of a high powered electrical appliance eg. Electric iron refrigerator oven etc to the earth wire of domestic circuit is called earthing. One key purpose of electrical earthing or grounding is that it can readily remove any excess energy from your main electric power system appliances and other electrical devices.

As mentioned our ground is a great conductor of electricity which means it.

Earthing in electrical network The main reason for doing earthing in electrical network is for the safety.

When all metallic parts in electrical equipment are grounded then if the insulation inside the equipment fails there are no dangerous. Why are domestic electrical appliances earthed. The object is to prevent the user of the appliance from being shocked if some accidental fault should occur within the appliance between the hot phase wire and the exterior casing of the appliance.

It does so by connecting the casing to Ground where the neutral is also connected. Earthing means to connect the metal case of an electrical appliance to the earth at zero potential by means of a metal wire called earth wire. It is used as a safety measure.

The main purpose of earthing an electrical appliance is to avoid the risk of an electric shock. Considering the safety reasons earthing is one of the main safety requirement in an electrical system. Minimizes risk of electric shock.

The main purpose of earthing is to avoid or minimize the chance of electrocution. Any leakage or faulty current in the circuit causes the presence of electric charge on exposed conductive surfaces. The earthing protects the apparatus and personnel from the high voltage surges and lightning discharge.

Earthing can be done by electrically connecting the respective parts in the installation to some system of electrical conductors or electrodes placed near the. Earthing is done to make the unwanted charges flow down to earth through a conducting wire. Earthing is the proper connection of exposed metal parts of an electrical circuit to the ground.

It is accomplished by thick copper wires. Earthing protects the appliances and human beings in case of insulation fail or accidental short circuit. What is the main purpose of earthing an electrical appliance.
