KPM VIT-100 Vacuum Interrupter Tester

Smart, compact, and lightweight — the ultimate DC high-voltage withstand testing solution for vacuum interrupters and circuit breakers.

Product Overview

The KPM VIT-100 (Vacuum Interrupter Tester) is applied for vacuum interrupter or vacuum interrupter circuit breaker high-voltage withstand tests. The test results are used to determine whether the VI or the VI of the circuit breaker is still in a healthy condition.

The tester can generate DC high voltage up to 60kV on both sides of the VI. At the same time, it samples and displays the leakage current flowing through the VI. The leakage current value is used to evaluate whether the VI remains in good condition.

The KPM VIT-100 is smart, compact, and lightweight. Its operation is also very simple, making it an ideal tool for vacuum circuit applications in power utility construction and maintenance departments. It can also be used as a quick quality control tool for vacuum interrupter and circuit breaker manufacturers for VI high-voltage withstand tests.

Key Highlights

DC High Voltage up to 60kV

Test Connection

Proper connection of the KPM VIT-100 to the vacuum interrupter is essential for accurate and safe testing. Follow the procedure below carefully.

01

Connect DC Voltage Output

Connect the DC voltage output terminal of the tester to one side of the vacuum interrupter (VI) using the high-voltage cable provided.

02

Connect Leakage Current Input

Connect the other side of the VI to the leakage current measurement input terminal of the tester to complete the measurement circuit.

03

Ground the Tester

Connect the tester's ground terminal to earth ground to ensure safe operation and accurate readings throughout the test.

04

Set Test Voltage

Click the "Test Voltage" button in the test setting window to configure the desired test voltage from the main menu. The valid high-voltage withstand time range is 1–60s.

Test Voltage Settings

The KPM VIT-100 provides six quick test voltage levels accessible directly from the main menu. Each level covers a defined adjustable voltage range, allowing operators to quickly configure the appropriate test voltage for their application. The valid high-voltage withstand time range is 1–60 seconds.

1

First Voltage Level

Adjustable range: 5–10kV

2

Second Voltage Level

Adjustable range: 11–20kV

3

Third Voltage Level

Adjustable range: 21–30kV

4

Fourth Voltage Level

Adjustable range: 31–40kV

5

Fifth Voltage Level

Adjustable range: 41–50kV

6

Sixth Voltage Level

Adjustable range: 51–60kV

Voltage setting resolution is 1kV per step. Click the "Test Voltage" button in the test setting window to access and configure these levels from the

main menu.

Test Time & Current Settings

Test Time Setting

Time Configuration

The valid adjustment range for the high-voltage withstand test time is 1 to 60 seconds. Operators can set the desired duration within this range to match the requirements of the specific test standard or application being performed.

Test Current Setting

Overcurrent Protection

The test current setting on the KPM VIT-100 is used to adjust the maximum allowable leakage current during a test. The valid adjustment range is 1–300µA.

If the leakage current flowing into the tester through the input terminal exceeds the preset value, the tester will automatically enter protection mode and display an overcurrent protection message, safeguarding both the equipment under test and the operator.
