| Abstract: | In this paper, a fiber optic sensor utilizing the Pockels effect of Bi 12 SiO 20 is devised, and an electric field measuring system is developed for the measurement of 50Hz electric field in transformer oil. By using this measuring system, the electric field in oil of a plane plate, model bushing and at the lower part of 220 kV transformer bushing is measured. Comparing the measured data with calculation results, it is proved that this measuring system can be used for electric field measurements in oil filled power equipment. |
