Why it's important to test vacuum interrupters (aka vacuum bottles)
All vacuum interrupters (aka vacuum bottles) increase in internal pressure over time. The pressure increase may be due to small, long-path leaks from outside to inside, diffusion through the container materials and/or virtual leaks from materials within the internal volume. Vacuum interrupter manufacturers design and test their vacuum interrupters for a minimum lifetime of twenty to thirty years. Vacuum interrupters may successfully operate beyond this period but it is beyond their design life.

Since the first large influx of vacuum interruption in the early 1970s, the technology has become the most widely applied power interruption technique in the medium voltage range (2.4kV-38kV). Vacuum technology now dominates the interrupter market throughout the world. This means that there are hundreds of thousands of breakers and contactors that use vacuum interrupters in use that were manufactured twenty or more years ago. Inevitably, in-service vacuum interrupter failures caused by vacuum loss have greatly increased over the last ten years.

Consequently, on-site or shop testing of vacuum interrupters is necessary to identify potential problems before failure occurs. Vacuum Interrupters offers the VITS60M and VITS75M, traditional high voltage dc pass/fail testers, and the MAC-TS4 which determines the internal presure of the vacuum interrupter to predict it's useful life.
If you've already have a vacuum interrupter failure
If you've already have a vacuum interrupter failure, we can provide you a replacement vacuum interrupter (vacuum bottle interrupter), for virtually any manufacturers' medium voltage circuit breaker or contactor.
