Integrated Detection of Temperature and Partial Discharge on Cables Based on FBG

Fiber Bragg Grating (FBG) is being studied by more and more researchers in the field of electrical engineering. An integrated detection system for temperature and PD on cables based on FBG is proposed. At the same time, the method of eliminating cross-interference between temperature and PD is put forward, which ensures the accuracy of detecting temperature and the sensitivity of detecting PD. A PD detection experiment shows the detection system can detect the PD with high amplitude. And the calculation of wavelengths corresponding to the peak of reflection spectrums verifies the effectiveness of the integrated detection method.
