VBT-60/VBT-80

vacuum bottle testers

The VBT-60 and VBT-80 are microprocessor-based, portable, dc (60 kV and 80

kV, respectively) vacuum bottle testers. These lightweight, portable testers are

designed for testing circuit-breaker vacuum bottles in the fi eld and at the shop.

Test voltages can be selected from 10 kV dc to 60 kV dc in 5 kV steps for the

VBT-60 and from 10 kV to 80 kV dc in 5 kV steps for the VBT-80. 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. If a fl ash-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-60 and VBT-80 feature a back-lit LCD screen (16 characters by 2 lines)

that is viewable in both bright sunlight and low-light levels. A turn-and-press

knob is used to control the unit. An RS-232C interface port is provided for factory

calibration and diagnostic testing.

Each unit is furnished with a 10-foot test cable that is terminated with a quickdisconnect

test clip. A transportation case is also included.
