An Overhead Conductor Weighing Sensor Based on Fiber Bragg Grating

Abstract:

Snow and ice disasters on power system safe and reliable operation of the transmission line has a great threaten.An overhead conductor tension sensor based on fiber Bragg grating is developed.The sensor contains a strain sensor module and a temperature compensation module which can offer temperature compensation for strain sensing module.The sensor connected to the tower and the insulator with metallic clamps.If there is ice on the transmission line,the tension of the sensor sensing module of the center wavelength will corresponding change,and the ice condition of the transmission wires can be reflected by the center wavelength variation.Experiment indicates that the tension sensitivity coefficient of the sensor is 9.8 pm/kN,the repeatability error is 1.78% FS,the nonlinear error is2.4% FS, the hysteresis is 1.5% FS.
