As electrical equipment insulation decrease and lead to breakdown caused by heat fault, fiber bragg grating sensor has many advantages such as high temperature, strong interference resistance, waterproof, long distance fiber optic transmission, has being applied broadly. Herein, this paper introduces some typical monitoring schemes which has practiced in electric power, railway, bridge and tunnel, power and many other fields. According to the traction substation test data, temperature resolution of 0.1℃, error within ± 2℃, high alarm sensitivity. This findings dates suggest that the technology has high reliability and stability, and it is very practical for high voltage equipment key parts of insulation monitoring.
