| Abstract: | The topology and operational principle of FOCT(Fiber Optical Current Transducer) are introduced and several factors affecting its temperature performance are analyzed:the larger circular birefringence and smaller linear birefringence of fiber sensing coil,Verdet constant of sensing fiber and the quarter-wave plate error parameter.Methods to avoid the influence of temperature on FOCT performance are presented:the helically-wound sensing fiber to increase circular birefringence and decrease linear birefringen... |
