Paper Abstract

We have developed a prototype system of a fiberoptical distributed temperature sensor with high spatial resolution and have measured the temperature profile of the winding tempera-tures of a transformer model coil in operation. The coil is fabricated from a combined optical and electrical conductor with the optical fiber integrated into the electrical insulation. The results reveal strong variations between outer and inner conductors as well as outer and inner coil surfaces. A strong temperature gradient from the top of the coil to the bottom due to thermal convection can also be seen.
