Why is Electrical Earthing Necessary?

Have you ever received an electric shock while using any appliances under normal operating conditions? Almost everyone says yes; sometimes the shocks are mild, but they can cause damage to electrical and electronic devices and be dangerous to one’s life. Everyone should earth their premises properly to avoid any damage to human life or appliances.

Earthing allows one to protect their loved ones’ lives and appliances from electric shock by providing a path for fault current to pass or flow to the earth.

What is Earthing?

Earthing is a process or method of directly transmitting an electrical discharge to the ground via electrical cables and low resistance wires. To put it another way, earthing is the direct transfer of electrical charge to the earth. Earthing protects devices and the power system from failure and electrical damage. The primary function of earthing is to reduce the load when the electrical system overloads.

Advantages of earthing

The major advantages of electrical earthing are:

1. Ensures that electrical appliances and devices are safe from excessive electric current.
2. Aids in the direct flow of electric current within the ground.
3. Protects the electric appliance from damage.
4. It prevents building collapse due to lightning.
5. It protects against fire caused by an electric short circuit and saves goods from fire.
6. Earthing aids in overvoltage protection and voltage stabilization.
7. Earthing protects against electric current-related injury, damage, and death.
8. It aids in the prevention of fires in electrical installation systems.

It protects electrical appliances and devices from dangerously high levels of electric current. Even if the insulation fails, the earthing provides a path to the default current. The earthing prevents high voltage surges and lightning discharge from damaging the appliances. Earthing maintains a constant voltage in the healthy phase. It ensures the safety of any fire that may occur as a result of the current leakage.

 5 Important Benefits Of Electrical Earthing:

1.) Electrical Overload Protection:

One of the primary reasons for earthing electrical current is to protect yourself and your loved ones, which is one of the most important reasons. It also shields your home, appliances, and everyone from power surges. If lightning struck or a power surge occurred at your location for any reason, it could cause extremely high electrical voltages within your system, resulting in loss of life and property.

If you properly earth your home, any fault current or excess electricity will be transmitted to the earth rather than damaging life and property during an electric surge.

2.) Helps Direct Electricity:

If your home or business has a proper electrical earthing system, it means you will create easy paths for power to be directed straight where you want it, i.e. fault current to the earth, and it will help electrical currents travel safely and efficiently throughout your electrical system.
