Earthing Test
Earthing Value Testing, also known as Earth Resistance Testing or Grounding Testing, is a procedure used to measure the resistance of the earth electrode to the flow of electric current. It ensures that the grounding system effectively dissipates fault currents, preventing electrical hazards and ensuring safety in electrical installations.
Why Do We Need Earthing
Effective earthing is essential for the safe operation of every electrical system and the only way to ensure that earthing installations are effective and that they remain so, is to test them rigorously and regularly.
What is Earth Resistance?
The resistance of the earth electrode to the current flow into the earth is known as earth resistance. The resistance between the earth and the earthing plate is measured through a potential fall method.
Numerically, it is equivalent to the ratio of the earth electrode potential to the current disappeared by it. The resistance between the earthing plate and the earth is assessed through the potential fall method.
The earthing resistance value is based upon the soil resistivity, construction design, and climate-related conditions. Moisture in soil plays a critical role in the resistivity of the soil. Different types of codes indicate the desired value of an earthing system.
Why Should We Measure Earth Resistance
Safety: Measuring earth resistance helps find and mitigate potential electrical hazards, such as electric shock and fires. It ensures that the earth electrode system can effectively dissipate fault currents, preventing the buildup of dangerous voltages and protecting individuals and equipment.
How Frequently We Should Measure Earth Resistance
It typically involves checks of the presence, appropriate redundancy, suitability and visible condition of earthing conductors, connections, surface layer materials and connected equipment and is typically recommended at intervals of between 1 and 3 years.
What Is The Acceptable Earth Resistance Value In India
The acceptable earthing resistance value in India is as follows: –
| (1) Earth Resistance of Power Station | 0.5 ohms |
| (2) Earth Resistance of EHT Sub-station | 1.0 ohms |
| (3) Earth Resistance of 33 KV Stations | 2.0 ohms |
| (4) Earth Resistance of D/t Structure | 5.0 ohms |
| (5) Tower Foot Resistance | 10.0 ohms |
