Vacuum Interrupters Inc. has introduced its new MAC-TS4 vacuum interrupter tester, the only test set capable of conducting predictive testing on vacuum interrupters in the field.
The MAC-TS4 is the third generation of the MAC product line. 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’ patented flexible magnetic field coil enables technicians to test most vacuum interrupters installed in the circuit breaker without having to remove the interrupter.
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 the field, shop or lab. Newest features include back-lit LCD display, detachable high voltage cable, built-in thermal printer, and PC compatibility. This PC friendly version can store hundreds of test results and allows the operator to download and generate reports.
