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.
The VCBA 01 offers an optional circuit breaker testing feature that can test the operating time on the circuit breaker main contacts. The test is initiated manually and then the instrument records the time from initiation of the test to the completion of the close or open operation of the circuit breaker. The highspeed data acquisition rate of the instrument during trip or close operation provides a 0.1ms resolution on the circuit breaker operating time. By setting the limit of the operating time in the test settings, the instrument can make a pass/fail determination.
The VCBA 01 features a user-friendly interface for comprehensively testing vacuum circuit breakers. The unit’s back-lit color LCD touch-screen (800 x 480 pixels) is viewable in bright sunlight and low-light and provides an intuitive menu structure where running a test is just few taps away. The full-sized industrial keyboard makes data entry very easy for information such as nameplate and setting information.
The VCBA 01 can store up to 100 test results internally. Test results can be transferred to a PC via the unit’s USB Flash drive interface (Flash drive not included) or directly via the USB 2.0 PC interface. The provided PC software can be used for analysis and report generation.
The VCBA 01 features a built-in 2” thermal printer for quick printout of results in the field.
