Fiber Grating Measurement of Temperature of GIS Bus Conductor

Abstract

This paper studies the principles of Raman scattering-based fiber temperature measurement technology and fiber Bragg grating-based (FBG-based) temperature measurement technology. In light of the situation of temperature measurement of GIS bus conductor, it compares the performance and technical indexes of Raman scattering-based temperature measurement scheme and FBG grating-based temperature measurement scheme. On this basis, it selects FBG temperature-measurement scheme for the temperature measurement of GIS bus contact.
