Abstract:
Accuracy decrease is one of problems that restricting engineering application of fiber optical current transformer (FOCT). The function of FOCT is introduced. The influence of temperature on the measurement results were studied and the dualway temperature compensation algorithm based on least square method were discussed. And its feasibility was verified by experiment. Analysis and experimental results show that this method improves the performance of FOCT in the whole temperature range.
