Abstract
A probe for use within a high voltage and high current electrical device is disclosed. The probe comprises an optical fiber, a substrate having a slot, and a photoluminescent material. The fiber has a first and second end and is configured to convey an activation light from the first to second end. A portion of the fiber is within the slot such that the slot receives the second end of the fiber. Emission of the photoluminescent material, as a function of temperature, is known. The photoluminescent material is disposed within at least a portion of the slot that faces the second end of the fiber so that they are in optical communication with each other. A change in intensity of a luminescent light emitted back into the fiber by the photoluminescent material when the activation light is conveyed by the fiber onto the photoluminescent material provides an indication of the integrity of the electrical device.
