WebEarth Injection Testing is a test of the earthing system and conducted to measure the risk of Earth Potential Rise (EPR) where a large current flows to earth through an earth grid impedance. Renewable Futures wanted … WebNov 3, 2024 · The principle of measurement is based on the U-I method (Ohms law) where the high DC current is injected to a test object and the voltage drop is measured across the test object. An example of the test setup during the ground grid integrity test is shown in the following figure: Figure 4. Ground grid integrity test using a high current DC source
