1.0 INTRODUCTION

1.1 General Description and Features

The VBT-75 S2 is Vanguard's second generation microprocessor-based, portable, 75kV 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 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. The test voltage and leakage current are displayed on the LCD

during testing. After the test time duration has elapsed and the leakage current did not pass the

pre-set 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-75 S2 features a back-lit LCD screen (20 characters by 4 lines) that is viewable in both

bright sunlight and low-light levels. A turn-and-press knob is used to control the unit. The VBT-

75 S2's firmware can be updated in the field via the unit's built-in USB Flash drive port.

The VBT-75 S2 is furnished with a 10-foot test cable that is terminated with a quick-disconnect

test clip. A transportation case is also included.

1.3 VBT-75 S2 Controls and Indicators

The VBT-75 S2’s controls and indicators are shown in Figure 1 below. A leader line with an index

number points to each control and indicator, which is cross-referenced to a functional

description in Table 2. The table describes the function of each item on the control panel. The

purpose of the controls and indicators may seem obvious, but users should become familiar

with them before using the VBT-75 S2. Accidental misuse of the controls will usually cause no

serious harm. Users should also be familiar with the safety summary found on the front page of

this User’s Manual.
