The VBT-75P is a microprocessor-based, portable 75 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 75 Kv dc in 1 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 and the leakage current did not pass the preset value of 100 μA, 200 μA, or 300 μA, the test voltage is returned to zero and a "Pass" message is displayed. 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 VOLTAGE” LED light. For additional operator safety, an “ARM” switch must be held down during testing.
The VBT-75P features a back-lit LCD screen (20 characters by 4 lines) that is viewable in both bright sunlight and low-light levels. A rugged, 16-key, membrane keypad is used to control the unit. Test results can be printed on the built-in 2-1/2" wide thermal printer.
The VBT-75P can store up to 84 records of 16 readings in Flash EEPROM. Test records can be retrieved and printed on the built-in thermal printer, or they can be transferred to a PC via the unit’s RS-232C interface. Windows?-based software is provided with each unit. Using this software, test records can be retrieved from the VBT-75P and then stored on the PC for future analysis and report generation. Additionally, test records can be exported in PDF, Excel, and XML formats.
The VBT-75P is furnished with a 10-foot test cable that is terminated with a quick-disconnect test clip. A transportation case is also included.
