Vacuum Interrupter Testing for Circuit Breakers

How to predict field life using vacuum interrupters

BY FINLEY LEDBETTER, Group CBS

Utilities have widely replaced older air-magnetic and oil interrupters for circuit breakers rated at one kilovolt (kV) or higher with vacuum interrupters (VI) due to higher interrupt capability. Vacuum interrupters also last up to 10 times the expected lifetime than newer sulfur hexafluoride (SF-6) gas interrupters. Unfortunately, the downside to building a protective device with a long service life is that utility...
