Contact Resistance Tester
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.
