Document Type and Number:
Japanese Patent JP5219816
Kind Code:

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.
