WebFeb 1, 2016 · A modified high-current method for testing the integrity of the grounding grid is proposed.. Quite different from conventional HCM, the modified HCM is an … WebJun 18, 2024 · When testing the resistance of a grounding system (rod, grid, etc), the objective is low resistance. The grounding electrode is expected to be capable of carrying large fault currents to ground, while safely diverting around the electrical system, equipment and people. Therefore, the requirement is quite simple: the lower, the better.
Substation Earth System Injection Testing - Ergon Energy
WebGrounding is a critical component of electrical systems. Effective grounding provides a low-resistance path for lightning and other phenomena that might otherwise damage electrical systems and injure personnel. A common method for measuring the resistance of a grounding system is the Fall-of-Potential test, also known as the 3-point or 3-pole test.
