Abstract
Techniques for detecting vacuum loss in a vacuum interrupter are disclosed. For example, a sensing system of a vacuum interrupter includes a sensor including a material that oxidizes in the presence of air and is at least partially positioned in an evacuated space of a vacuum interrupter, the sensor being configured to produce an indication of impedance of the material; and a control system coupled to the sensor, the control system including an electronic processor and an electronic storage that stores instructions that, when executed, cause the electronic processor to access an indication of impedance produced by the sensor, determine a measure of impedance of the material of the sensor based on the accessed indication of impedance, and determine a condition of the evacuated space based on the determined measure of impedance.
