  • What is Contact Resistance Test Why is Contact

    This test is especially important for contacts that carry large amounts of current (e.g. switchgear busbars) because higher contact resistance can lead to lower current carrying capacity and higher losses. In the case of a dry circuit connector, the test current should be low to prevent the joint to be melted by heat, (the current less than
