Paper Abstract

Fiberoptic techniques were first used to measure winding temperatures in power transformers more than ten years ago. Recently interest in such measurements to allow predictive loading and enhanced capacity utilization has increased. As a consequence, a new and more cost-effective fiberoptic temperature measurement system based on the fluorescent decay time technique has been developed for transformer use. The features of this system and its possible use in other power industry applications will be presented.
