The Vacuum Circuit Breaker Analyzer 01 (VCBA 01) is Power Diagnostic Instrument Company’s state-of-the-art, field portable, light weight instrument designed for the comprehensive diagnostic testing of vacuum circuit breakers. The VCBA 01 can perform high voltage DC vacuum integrity tests as well as operating time tests on the circuit breaker main contacts.
The VCBA 01 applies a test voltage to the vacuum bottle arcing chamber for the time specified in the test settings. While the test voltage is applied to the vacuum circuit breaker arching chamber, the instrument monitors the leakage current to the ground. If the leakage current to the ground remains lower than the set limit, the instrument registers the test as successful. If the leakage current exceeds the set limit, the instrument shuts down and removes the test voltage from the arcing chamber and registers the test as a failed test.
