Abstract
In recent years there has been considerable interest shown in the optical sensor design and multiplexing concepts. Optical fiber sensors have been successfully demonstrated for a variety of physical fields. The aim of our study was to demonstrate a temperature optical fiber sensor network for electrical engineering applications and especially for AC generators. The need was to monitor individually the temperature of the water boxes of the stator bars, and therefore, optical fiber sensors were attractive candidates due to their immunity to the high electric fields encountered inside these generators. Moreover, as you can have up to 200 points to monitor, we needed a sensor concept compatible with a multiplexing technique.
