Paper Abstract
We have developed an optical temperature sensor aimed at early detecting faults in Medium Voltage substations. The advantage of the sensor lies in its full suitability for the target application, which allows it to reach a cost compatible with the service rendered. Heavily doped ruby has shown to be attractive (fluorescence efficiency, cost) but also revealed a multi-fluorescence lifetime behavior. Accuracy of +/- 2 degree(s)C has been achieved over the -20 degree(s)C/+120 degree(s)C range for a 12 point sensor. We hope this system opens up interesting prospects in the field of thermal diagnosis, beyond its application in electric power industry.
