The HVBT-80 is a microprocessor-based, portable 80 kV dc vacuum bottle tester. This lightweight, portable tester is designed for testing circuit-breaker vacuum bottles in the field and at the shop.
Test voltages can be selected from 10 kV dc to 80 Kv dc in 5 Kv steps.
The high-voltage test time can be set from 5 seconds to 2 minutes. The test voltage is raised to the selected voltage and held for the test time duration. After the test time duration has elapsed, the test voltage is returned to zero. If a flash-over condition occurs, such as bottle failure, the test voltage is immediately turned off, a "Failure" message is displayed on the LCD screen, and the "TEST FAIL" LED light on the unit is also illuminated.
The presence of high voltage is indicated by an audible tone and an illuminated "HIGH VOLT-AGE" LED light. For additional operator safety, an "ARM" switch must be held down during testing.
The HVBT-80 features a back-lit LCD screen (16 characters by 2 lines) that is viewable in both bright sunlight and low-light levels. A turnand-press knob is used to control the unit. An RS-232C interface port is provided for factory calibration andº diagnostic testing.
The HVBT-80 is furnished with a 10-foot test cable that is terminated with a quick-disconnect test
