全光纤电流互感器温度误差分析与温度误差补偿
Temperature error analysis and temperature error compensation of the all fiber optic current transformer
摘要
Abstract
The main source of all fiber optical current transformer temperature error is caused by λ/4wave-plate temperature error and the sensing fiber Verdet constant temperature error, this paper analyzes the relationship of the total temperature error, the λ/4 wave-plate temperature error and the sensing fiber Verdet constant temperature error, and derives the mathematical expression of them, and the curve fitting method is used to verify that the λ/4 waveplate initial phase delay angle is 86°;the theoretical analysis results are verified by the test system of FOCT temperature error.The theoretical analysis results and test results show that when the λ/4 waveplate initial phase delay angle is 86°, in the vast most of the temperature range the relative value of the error is less than 0.2%, which realizes compensation for temperature error.关键词
