description Publicationkeyboard_double_arrow_right Article 2012Publisher:MDPI AG Chao Tang; Tuan Liu; Lijun Yang; Ruijin Liao; Yuan Yuan; Fuzhou Zhang;SiO<sub>2</sub> hollow spheres and low relative permittivity insulation paper handsheets composed of these SiO<sub>2</sub> hollow spheres with different weight percentages were successfully prepared. Low-content SiO<sub>2</sub> hollow spheres were uniformly dispersed in the insulation paper handsheets. The relative permittivity of the immersed oil Kraft-SiO<sub>2</sub> hollow sphere handsheets (K-SiO<sub>2</sub>) initially decreased and then increased with increased amount of SiO<sub>2</sub> hollow spheres. K-5% SiO<sub>2</sub> possessed the lowest relative permittivity of approximately 1.68 at 50 Hz. The breakdown voltage of the paper-oil-paper composite insulation system increased from 26.4 kV to 30.5 kV with decreased relative permittivity of the paper from 2.55 to 1.68. The relationship between the relative permittivity and electric field strength of typical samples were also calculated.

Authors: Pang Fubin; Yuan Yubo; Bo Qiangsheng; Ji Jianfei;In this paper the origin problem of data synchronization is analyzed first, and then three common interpolation methods are introduced to solve the problem. Allowing for the most general situation, the paper divides the interpolation error into harmonic and transient interpolation error components, and the error expression of each method is derived and analyzed. Besides, the interpolation errors of linear, quadratic and cubic methods are computed at different sampling rates, harmonic orders and transient components. Further, the interpolation accuracy and calculation amount of each method are compared. The research results provide theoretical guidance for selecting the interpolation method in the data synchronization application of electronic transformer.
