Abstract

In this paper, the measuring principle of the distributed optical fiber Raman temperature sensing technology (DFOTST) is introduced, and the temperature distribution characteristics of the power transformer windings are studied. Further more, the temperature distribution is calculated for a given testing object SF-31500/110 power transformer. Then the experiments of temperature measurement for determining its temperature spatial resolution and range measurement are performed in library environment, and the result data is analyzed. All above provide a basis for further research
