“We are extremely proud to have the new MAC-TS4 recognized as this year’s Safety Monitoring Device Product of the Year and believe this honor is a testament to the dedication and innovative spirit of our team,” says Finley Ledbetter, CEO and chief scientist of Group CBS. (Vacuum Interrupters, Inc. is an affiliate company of Group CBS.) “Until now, the only accepted field-service test for vacuum interrupters has been a simple pass/fail test performed with an AC high-potential (HiPot) test. The MAC-TS4 is provided with everything required to determine the pressure of your vacuum interrupter in the field, shop or lab.”
The MAC-TS4 vacuum interrupter test set can easily determine the pressure inside a vacuum interrupter and, along with wear and number of operations, can predict the usable life of the vacuum interrupters used in your circuit breakers and contactors. Until now, this type of testing could only be done at the assembly plant. The MAC-TS4 uses magnetron atmospheric condition (MAC) testing to measure actual ion current against known values to determine vacuum interrupter internal pressure. The MAC-TS4 test set can help avoid unnecessary damage to circuit breakers and contactors by identifying interrupters approaching an unsafe pressure.
Vacuum Interrupters, Inc.‘s patented flexible magnetic field coil enables technicians to test most vacuum interrupters installed in the circuit breaker without having to remove the interrupter.
