What is Key difference between Earthing and grounding ?



  Earthing 

1. Earthing is used to connect conductive parts of electrical appliances to the earth. Conductive parts are body or frame of electrical appliances which is not carrying any current during the normal condition.

2. In case of earthing connection carried out between metallic body or frame of electrical appliances and earthing plate in the ground through earth wire with earthing lead.

3.Type of earthing is pipe earthing, water main earthing, plate earthing, Strip wire earthing, and rod earthing.

4. In the case of earthing, the green wire used for mostly wiring work, and also green with the yellow strip is used or a bare conductor is used for earthing work.

5. Earthing provides a path to the large surface to zero potential.

6. In case of earthing, Zero potential is due to a strong physical connection between the ground and body of electrical appliances.

7.Earthing is used for the protection of the human body from electrical shock and also used to discharge unwanted electric charges to the ground from electrical appliances.

8. It is used to earth the metallic body or enclosures of electrical installation like transformers body, motor body etc.

9. It is used to provide protection from electrical shock and fault in the system.

10. Earthing draws unwanted electrical current to the earth during the fault condition and protects the human body from electrical shock.


Grounding

1. Grounding is used to connect the current-carrying part of the electrical system to the earth electrode which is buried in the ground through an earth wire.

2. Grounding is the connection between the current-carrying system to the ground. It is neutral which is provide a return path for current.

3.Types of grounding are reactance grounding, resistance grounding, and reactance grounding.

4. In grounding wire used is green with yellow stripes or bare conductor.

5.Grounding provides a return path for the current during fault conditions or abnormal conditions.

6.In case of Grounding, Neautral connected to the earth has some potential. it is not having zero potential.

7. Grounding protects electrical equipment and power equipment during fault conditions and provides a return path for phase currents.

8. Example of grounding is a neutral point of a star-connected current transformer.

9. Grounding is used to balance the unbalanced load in the system and protect the system.

10.Grounding is provided a return path to the current between electrical equipment and the power system.
