    NEW - Vacuum interrupter conditioning to extend the life of vacuum interrupters Extending the Life of Your Vacuum Interrupters
For years we have been working to develop a process that conditions and extends the life of vacuum interrupters by removing unwanted gas molecules from within the canister. The process has been proven in the lab and in the field. We are now able to extend the service life of vacuum interrupters by keeping the internal pressures within an acceptable range for an extended period of time. Our goal is to keep vacuum interrupters in service for more than 100 years.

    Vacuum Interrupter Testers
MAC-TS4 Vacuum Interrupter Test Set
Uses Newest Test Technology To Predict Usable Life of Vacuum Interrupters

Vacuum Interrupters Inc. provides the MAC-TS4 vacuum interrupter tester, the third generation test set using its patented technology for determining the condition of vacuum interrupters in the field, shop or laboratory. This is a Magnetron Atmospheric Condition (MAC) vacuum interrupter test set which utilizes the latest technology to predict the usable life of a vacuum interrupter. Covered by United States Patent numbers 9,032,795 and 9,026,375. If you're looking for the most meaningful vacuum interrupter bottle test, take a look at the outstanding capabilities of our high technology vacuum pressure integrity tester, the MAC-TS4 vacuum interrupter test set.

VITS60M 3-In-1 Multifunction Test Set
Includes Traditional Vacuum Interrupter Integrity Tester For Go/No-Go Pass/Fail Test Results, 2.5/5/10kVdc Megohmmeter and 60kVdc HiPot

Our newest vacuum interrupter integrity tester (aka vacuum bottle tester) is the unique, user-friendly VITS60M. This test set uses the traditional NETA/ANSI/IEEE high voltage dc test for vacuum interrupters to provide basic Go/No-Go Pass/Fail test results. The VITS60M is a rugged, light-weight, completely self-contained tester which incorporates both a 1kVdc-60kVdc high potential test set optimized for testing vacuum interrupters and a 2.5/5/10kVdc megohmmeter for insulation resistance tests. Check out the details of the VITS60M vaccum interrupter integrity tester which uses traditional pass/fail test technology.

    Instrument Transformer Test Set
New CTVT-45 CT and VT/PT instrument transformer test set CTVT-45 Two-In-One Instrument Transformer Tester New CTVT-45 CT and VT/PT instrument transformer tester
Tests both CTs and VTs/PTs

We just introduced our unique, 2-in-1 CTVT-45 instrument transformer test set. It quickly and accurately tests both current transformers (CTs) and voltage transformers (VTs), aka potential transformers (PTs) in the field or lab.

It's a rugged, lightweight, user-friendly tester that performs basic and routine maintenance testing of instrument transformers. Use this link for more details of the CTVT-45 instrument transformer test set.

    Circuit Breaker Timer and Timer Interface Units
Our multifunction CBT-1201 circuit breaker timer and CBTI-1201 circuit breaker timer interface units are designed to operate and interact with all types of circuit breakers.

Both units incorporate a 120VAC/120VDC power supply for charging, opening and closing spring charged breakers while outside their cubicle and are available with unique cable sets which significantly simplify and speed connections to the circuit breaker under test. Both units also have provisions to accept and distribute variable voltages from an external power supply.

The CBT-1201 circuit breaker timer unit incorporates a built-in timer which captures trip, close and bounce times. The CBTI-1201 circuit breaker timer interface unit is designed to easily and quickly interface with an external timer.

These circuit breaker testers are covered by United States Patent number 9086447.

Use the following links for additional information on the circuit breaker timer or the circuit breaker timer interface unit.

    If You Already Have Had A Vacuum Interrupter Failure
