  • Vacuum Circuit Breakers Testing Methods - Switchgear

    2019-9-17Vacuum Circuit Breakers Testing Methods. When vacuum interrupters are manufactured or used in field there are three tests used to validate their function :1: contact resistance, 2:high potential withstand, 3:The leak-rate test. Contact Resistance Test :A micro-ohmmeter is applied to the closed contacts of the VI and the resistance is measured
