Downloaded from: justpaste.it/470ze Fluke Distributor in Bangalore An earth tester is a device used to measure the earth resistance or the ground resistance of electrical systems. This is crucial in ensuring that the grounding system of electrical installations is safe and effective, helping prevent electrical shocks and equipment damage. Types of Earth Testers: 1. Fall-of-Potential Earth Tester: Uses two auxiliary electrodes to measure potential difference. 2. Clamp-Type Earth Tester: Measures resistance w ithout disconnecting the ground system, useful for quick tests. 3. 4-Terminal Earth Tester: Offers higher accuracy, commonly used in professional settings. How It Works: The tester sends a current through the ground and measures the potential difference. The resistance is calculated using Ohm’s Law: R=VIR = \frac{V}{I}. Applications: Electrical substations Industrial facilities
