[Abstract]:The error of commercial all-fiber current transformer (FOCT) is generally less than 0.2%. The signal processing method is the key factor to determine the measurement accuracy of this kind of sensor. This paper discusses the optical circuit structure, working principle, technical advantages and interference signal characteristics of all fiber current transformer, puts forward an all fiber current transformer detection system based on digital open loop and its realization scheme, and discusses its working principle and characteristics. The test results show that the detection method improves the performance of all fiber current transformer and makes it meet the accuracy requirements of electronic current transformer for 0.2 grade measurement. It has great reference value for solving the problems of signal processing, measurement accuracy and measurement sensitivity of all-fiber current transformer.
