Vacuum Bottle Tester 75KVDC VBT-75 S2

Adiradh offers electrical testing equipment for circuit breaker maintenance, inspection, and diagnostic applications. The 75 kV DC Vacuum Bottle Tester VBT-75 S2 is designed to assess the condition of vacuum interrupters used in circuit breakers. Moreover, it supports testing in both field and workshop environments. The instrument applies a selected high DC voltage to the vacuum bottle and monitors leakage current during the test. Therefore, maintenance teams can evaluate the test response and identify bottles that require further investigation. In addition, the tester provides automatic test operation and digital voltage and current readings. Its programmable leakage-current thresholds support defined pass/fail assessment. Furthermore, the instrument includes a backlit LCD for viewing test information under different lighting conditions. The portable design also supports use at different testing locations. Consequently, the VBT-75 S2 is suitable for electrical maintenance teams, switchgear service providers, and testing professionals working with vacuum circuit breakers. Adiradh provides product information to help buyers evaluate electrical testing instruments according to their technical requirements.

Overview

The VBT-75 S2 is a microprocessor-based, portable vacuum bottle tester with a maximum output of 75 kV DC. It is designed to test vacuum interrupters installed in circuit breakers. The instrument offers selectable test voltages from 10 kV to 75 kV DC in 5 kV steps. Moreover, users can select a test duration ranging from 5 seconds to 2 minutes. During testing, the instrument displays the applied voltage and measured leakage current. In addition, users can select leakage-current thresholds of 100 µA, 200 µA, or 300 µA. When the test meets the selected conditions, the instrument displays a pass result. However, if a flashover occurs, the instrument stops the high-voltage output and indicates a failure. The backlit LCD supports operation in bright and low-light environments. Furthermore, the tester includes an audible high-voltage warning and an illuminated warning indicator. Its USB flash drive interface supports field firmware updates. Therefore, the instrument provides essential functions for vacuum bottle testing in maintenance workshops and field service applications.

About Product

The VBT-75 S2 vacuum bottle tester evaluates the electrical response of vacuum interrupters through a controlled high-voltage DC test. Vacuum interrupters form an important part of vacuum circuit breakers because they interrupt electrical current during switching operations. Therefore, checking their condition is an important part of suitable maintenance procedures. The tester applies a selected DC test voltage and monitors leakage current throughout the programmed test period. Moreover, the instrument displays both parameters on its LCD screen, allowing technicians to observe the test conditions. The selectable voltage range extends from 10 kV to 75 kV DC in 5 kV increments. In addition, the user can configure the test duration and leakage-current threshold. The instrument then provides a pass or fail indication according to the test conditions. If a flashover occurs, it shuts off the high-voltage output and displays a failure message. However, test results should be interpreted according to the circuit breaker manufacturer’s instructions and the applicable maintenance procedure. The instrument is intended for trained electrical testing personnel who follow suitable high-voltage safety precautions.

Technology & Benefits

The VBT-75 S2 uses microprocessor-based control to manage its vacuum bottle testing sequence. First, the operator selects the required DC test voltage, test duration, and leakage-current threshold. Next, the instrument raises the output voltage to the selected level and maintains it for the programmed period. Meanwhile, the LCD displays the test voltage and leakage current. Moreover, the instrument evaluates the measured current against the selected threshold. If the test conditions meet the configured acceptance criteria, it displays a pass message and returns the test voltage to zero. However, if a flashover occurs, the tester immediately switches off the high-voltage output and activates its failure indication. In addition, an audible tone and illuminated indicator warn the operator when high voltage is present. An ARM switch must remain pressed during testing, providing an additional operating safeguard. The backlit LCD improves visibility in different lighting conditions. Furthermore, the portable housing supports field and workshop use. The USB flash drive interface allows firmware updates in the field. Consequently, these functions support controlled testing, clear result indication, and practical maintenance workflows.
