The hot-spot temperature on-line measurement for transformer winding has significant meaning for identi-fying the insulation condition of power transformer.In this paper, a novel temperature measurement method based on fiber grating is presented.The principle is introduced at first, and then the configuration and key technology of the temperature measurement system are discussed.Finally, aiming at different demands of the customers, different in-stallation structure are designed and tested.The testing results show that the proposed method is able to realize real-time measurement for the winding temperature changes, which will provide powerful support for the insulation condi-tion evaluation of power transformer.
