3. Introduction Electrical earthing is the process of safely diverting electrical energy into the ground using a low-resistance wire . Earthing system discovered by German scientist  C.A. von Steinheil  in 1836–1837. What is electrical earthing system? Who discovered earthing system?

4. Types of Electrical Earthing Systems TN (Terrestrial-Neutral) System In this system the neutral point of the power supply is directly linked to the earth. This commonly used in low-voltage installations, like homes. The terrestrial connection is made by burying a metal rod or plate in the ground near the house. This metal piece helps connect the electrical system to the earth. Neutral Connection Inside the house, the neutral wire from the electrical supply is connected to the earth electrode through the earthing conductor.

5. TT (Terrestrial-Terrestrial) System Each individual device is connected to its own earth electrode this system .every machines in a factory has its own earth connection .every machine are connected a metal rod buried in the ground nearby. This system is commonly found in industrial settings, such as factories or manufacturing plants. M1 M2 M3

6. IT (Isolated-Terrestrial) IT (Isolated-Terrestrial) earthing systems are used in specialized environments like hospitals, data centres, and telecommunications facilities. They ensure safety and reliability. System The electrical system is isolated from the ground and can any earth fault currents are detected by monitoring systems.

7. Components of Earthing System Earth Electrode: Earthing Conductor : Earth Pit: This is like a metal stick buried in the ground. It's the link between the electrical system and the earth. It's a wires that connects the earth electrode to the electrical system or equipment. Think of this as a box buried in the ground where the earth electrode connection is kept.

8. The main purpose of electrical earthing is to ensure safety Preventing electric shocks. Protecting equipment from damage. Dissipating lightning strikes and power surges. Promoting stable operation of electrical systems. Purpose of Earthing
