Abstract
A apparatus for detecting a high pressure condition within a high voltage vacuum device includes a microcircuit embedded within the vacuum containment that transmits a wireless signal upon detection of a high pressure condition and/or light generated by arcing between the electrical contacts of the high voltage device. The wireless signal can be transmitted via RF or optical means. The microcircuit is powered by energy sources produced within the vacuum device such as magnetic fields generated by current flow through the device, or light generated by arcing between the contacts. Alternatively, the microcircuit can be powered RF or optical signals transmitted to the microcircuit from outside the vacuum device.
