  • Thermal modeling of the power transformer to estimate the internal temperature only reflects the winding hot spot to a certain extent. The application of optical fiber sensors to measure transformer internal temperature directly can obtain the true temperature with high accuracy and stability and overcome the shortcomings of traditional electric sensors. It analyses the measuring principle of FBG(fiber bragg grating)sensor, and constructs transformer internal temperature measureme.....。
