First In-House Manufactured Certified Vacuum Interrupters Go To Market
In the first quarter of 2021, Vacuum Interrupters shipped its first set of certified vacuum interrupter replacements that were manufactured in-house. Click to read more.
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.
CBT-1202 Circuit Breaker Timer Now Available
Everything you need to easily perform breaker timing tests is included in this universal, light-weight ciruit breaker timer which captures and stores trip, close, and bounce times in milliseconds. Features include:
CTVT-45 Two-In-One Instrument Transformer Test Set Announced
This is a unique, multi-function tester which incorporates the necessary capabilities to test both current transformers (CTs) and voltage transformers (VTs/PTs) in the field or shop. Comprehensive tests are performed in accordance with applicable ANSI and IEC test standards. Lightweight, rugged and user-friendly, the CTVT-45 sets a new standard in instrument transformer test equipment for field use. Use the following link for more details on the CTVT-45 instrument transformer tester.
VITS60M 3-In-1 Multi-Function Test Set Introduced At 2018 PowerTEST Conference
Not only tests the integrity of vacuum interrupters, the VITS60M also is a 60kVDC hipot and a 2.5/5/10kV megohmmeter that in addition to measuring insulation resistance also provides automated test routines for polarity index and absorption rate tests.
