| Abstract: | For resolving the difficulties on the instability of optical fiber current transformer, a novel current-temperature sensing scheme is presented. It has the theoretical advantage of eliminating the problem of instability .The mathematical model of the sensing system is established to analyze the steady and transient characteristics. An experimental current transformer is constructed for testing. Theoretical analysis and experimental results show that this scheme is available if appropriate technique are used. |
