A moisture sensing technique for real-time monitoring of the content in transformer oil based on an S-taper fiber structure, is proposed and experimentally demonstrated, with advantages high sensitivity, excellent repeatability, simple fabrication, compact resistance to ambient temperature variation. By analyzing physical model fiber, quantitative relationship between wavelength change transmission dip spectrum established. Then, fibers different structural parameters, such as waist diameter...
In recent years, bushing life is the main concern in transformer research, which related to its hot spot temperature. It very important for stable operation of and power system carry out effective thermal management according temperature distribution bushing. view problem insufficient analysis under influence solar radiation dielectric loss, a 110kV oil-paper capacitor studied this paper, corresponding model established analysis. The effects loss on surface are basis current heat solid...
