Abstract
A method and apparatus for detecting a high pressure condition within an interrupter includes introducing high intensity ultrasonic sound into the outer wall of a vacuum interrupter through a sonic wave guide, then listening for the reflected and retransmitted response signals. The characteristics of the response signals are utilized to determine the pressure within the interrupter, and to determine when an unwanted high pressure condition exists.
