How does grounding electricity work?

Electrical grounding is one of the most common methods to solve the problem of electrical leakage outside of electrical equipment. The purpose of electrical grounding is to ensure the safety of people when using electrical equipment. So how does electricity grounding work?

What is electrical grounding?

Why should electrical equipment be grounded?

The meaning of electrical grounding is to ensure the safety of electricity users. The metal housing of electrical equipment must be connected to the ground wire. Especially when using washing machines and refrigerators, it is necessary to have a ground wire.

Electrical grounding is a backup path that provides an alternating path for current to flow back to ground if there is a fault in the wiring.

Grounding is to reduce the amount of current flowing through the body to a level that is not harmful to humans; This happens when non-voltage-carrying materials such as chassis, case due to phase insulation that the shell is damaged, resulting in live charge.

Some appliances related to water or high humidity as refrigerators, washing machines, and bathroom appliances should all be insulated. Water conducts electricity very well; if the human body comes into contact with water carrying an electric current, it will cause electrical accidents.

If the electric motor and electrical circuit in the washing machine get wet or for some other reason its insulation is reduced. It will cause an electrical leak. This cause the metal outer shell and inside of the washing machine to carry electricity. Similar to other devices, dangerous to the user.

How to ground electricity??

The way to perform protective grounding will require wires with a resistance level of no more than 4 ohms. This helps the ability to ground to bring the best effect. The reason is that the current will pass through the compact electric wire, through the human body and transmitted to the ground.

In apartments, people can use metal door frames with concave legs as grounding feet.

You can use metal wire to connect from the case of electrical equipment and make direct contact with the metal frame.

How does grounding electricity work?

Grounding works by taking advantage of the electronegative properties of the ground. The ground on which you walk has a negative charge. Therefore, it can neutralize the positive charge. Grounding allows excess electricity to discharge through the ground.

Most electrical systems have a ground wire. You can find ground wire in car batteries, electrical outlets, home appliances, and more. The ground wire is specially designed to connect to the ground. Due to the electronegative nature of the ground, it is possible to discharge excess electricity.

Most electrical systems are electrically grounded. Grounding ensures that any excess electricity is discharged. Excess electricity will take the path of least resistance, which will be the ground wire running to ground. Although there are different ways to ground an electrical system, most of them consist of a ground wire and a metal rod.

Conclusion

After reading this section, you will have a better understanding of electrical grounding and how does grounding electricity work. Electrical grounding is the process of conducting excess electricity to the ground through a conductor. The ground wire will safely discharge excess electricity to the ground without causing injury or fire.
