    Ground Resistance Testing

    The connection resistance between the accessible metal parts of the electrical appliance and the grounding terminal or grounding contact. The ground resistance test is one of the important safety performance tests of electronic and electrical products, used to quantitatively evaluate the grounding continuity of electrical appliances, with the resistance value indicating the reliability of the grounding capability. A grounding resistance that is too large may still cause harm to the human body, otherwise, it functions as protection.
