Test products: Vacuum Interrupters Inc. offers the VITS60M vacuum interrupter integrity tester (aka vacuum bottle integrity tester). First and foremost, the VITS60M is an extremely user-friendly, very portable, light-weight 60kV dc test set that includes everything required to test the integrity of vacuum interrupters in the field or shop. It incorporates a variable high-voltage power supply, back-lit LCD display, comprehensive safety features; and is furnished with a complete set of test cables.

Actually, this is a 3-in-1 test set as it additionally has superior performance as a 2.5/5/10kV megohmmeter; and can also function as a stand-alone 60kV dc hipot. As a megohmmeter it not only measures insulation resistance, it also provides automated test routines for polarity index and absorption rate tests.

The main objective of the unique design and simple operation of the VITS60M is to permit the test technician to use a single test set to easily test vacuum interrupters as well as insulating elements in the field during maintenance testing. Armed with this information, users can determine if a vacuum circuit breaker, contactor or other electrical equipment should remain in service or must be repaired or replaced.

Utilizing the traditional NETA/ANSI/IEEE high voltage dc test for vacuum interrupters, the VITS60M provides a 1kV-60kV dc test voltage for basic Go/No-Go Pass/Fail test results.

The unit's LCD display indicates:
• Test duration
• Test voltage being applied
• Measured leakage current
• Whether the vacuum interrupter passed or failed the test
• In addition to results being shown on the LCD display, panel lamps also indicate the Pass or Fail condition of the vacuum interrupter

The VITS60M also can function as a megohmmeter and provides 2.5/5/10kV dc for performing insulation resistance tests of various insulating elements of the circuit breaker, contactor or other electrical equipment under test.

Automated test routines are incorporated for polarity index and absorption rate when the VITS60M is performing as a megohmmeter/insulation resistance tester. The test set provides programmable leakage current thresholds and test durations.

The unit's LCD display will show:
• Test duration
• High voltage being applied
• Current and resistance values being measured
• The unit will also calculate and display: Absorption ratio, Polarity index of the element being tested
