Contact Resistance Tester / Ductor Testing The contact resistance is the resistance to the current flow in electrical connections, due to surface conditions in the connection o contact surface, which may lead to poor or bad connection if it is too high, causing different problems in the circuit. Therefore, the contact resistance test measures the resistance of electrical connections in switching devices, breakers, relays, joints, connectors, etc, for finding bad or corroded contacts as a preventive method, or for diagnosis and problem solving.The contact resistance test is very important for contacts that carry large amounts of current (e.g. circuit breakers, busbars, cable
