摘要: A simple embedded-Fiber Bragg grating (FBG) based smart bolt is proposed to realize the loosening monitoring with high accuracy in power grids. The calibration and experimental results application demonstrated its reliability. At same time, bolts installed at connections of a transmission line tower showed capability galloping, which also concerned event
