The Application of a Fiber Bragg Grating Temperature Detector in the Long-Distance Surveillance of Transformer Hotspots

A transformer is a key equipment of an electrical system and its long-term online surveillance is quite significant.This paper introduces a new fiber Bragg grating temperature detector to surveil the temperature of the a transformer hotspot,in which we employ an advanced FBG sensing technology,and which has such positives as electromagnetic interference immunity,long-distance surveillance and high accuracy,especially suitable has been for such scenario as high voltage and strong magnetic field.It put into practice in many substations and the satisfactory results has been achieved,and it is a better the solution to the problem of the inaccuracy of other traditional temperature detectors.
