Vacuum Interrupters MAC-TS4 predicts usable interrupter life
By Alyssa Dalton
March 19, 2014 – Vacuum Interrupters has announced its MAC-TS4 vacuum interrupter tester, which claims to be the only test set capable of conducting predictive testing on vacuum interrupters in the field.
The device uses magnetron atmospheric condition (MAC) testing to measure the pressure inside vacuum interrupters and predict remaining life, in particular those approaching an unsafe pressure, says the company. New features include a backlit LCD display, detachable high voltage cable, built-in thermal printer, and PC compatibility.
