The Analysis on Temperature Characteristic of Fiber Optic Current Sensor Ratio Error
This paper researched on the error ratio of fiber optical current sensor (FOCS) induced by temperature drift.The principle about the influence of temperature fluctuation on FOCS was explained.Based on the principle,the math module of the influence of temperature on linear birefringence and the influence of linear birefringence on FOCS were established to deduce the math module of the influence of temperature on FOCS.By the math module,the reason of FOCS error drift was described to explain the relationship among temperature,linearbirefringence and FOCS ratio error.In the range of testing temperature,both the ratio error of FOCS and linear birefringence had a linear relationship with temperature.The experiment results conformed theoretical analysis.The FOCT ratio error had a linear relationship with experiment temperature 10~60℃.
