Abstract: A three-dimensional tension sensor based on fiber Bragg grating sensing technology is designed to monitor the stress state of substation bushing. In combination with finite element simulation and experiment, the three-dimensional tension sensor is implemented and signal demodulation is realized. It is shown that the tension sensitivities in three directions of the sensor are all between 0.01με·N-1 and 0.02 με·N-1, loading test results are basically consistent with the values of added load, and the average error of the sensor is 5.13% for the load of 0~600N. Therfore, the proposed tension sensor based on fiber Bragg grating is applicible in the measurement of three-dimensional tension with high accuracy.

Key words: fiber Bragg grating, three-dimensional tension sensor, high substation, voltage bushing
