Abstract Ground resistance testing is a fundamental and mandatory inspection for assessing the safety of electrical equipment and systems. A ground resistance tester evaluates the integrity of protective earth connections by injecting a standardized test current and accurately measuring the resultant resistance. This provides the critical quantitative data needed to prevent electric shock, lightni...
What is Ground Resistance? Ground resistance refers to the resistance encountered by current flowing from the grounding device into the earth and then dispersing to another grounding body or to the distant area. It includes the resistance of the grounding wire and grounding body itself, the contact resistance between the grounding body and the earth, as well as the resistance of the earth between ...
