Deteriorated insulators may lead to flashover or power failure in transmission lines, because of degradation in insulators strings' mechanism and insulation level after long periods of performing. By utilizing finite element method, E-field intensity and potential distribution of insulators strings with different resistance in different positions under the same pollution level have been researched...
As extremely important insulation support, insulators play a significant role in the transmission lines construction project. That the type of insulators varies with the environment condition can control the corridor width effectively. For now insulators of the II-type and the V-type are common used in the in-service transmission lines. By using the Y-type insulator, the corridor width of transmission...
Distribution of electric field and electrical potential in vacuum interrupter of 110 kV is simulated solving Laplace equation limited by certain boundary condition by the means of finite element method. Calculating results show that reasonable construction and arrangement of main shield, main share voltage shields, auxiliary share voltage shields, terminal shields and bellows shield could uniform...
There exists large-scale numerical computation in electromagnetic field which will turn to parallel computation in practical engineering application. Non-overlapping domain decomposition method (DDM) which is suitable of parallel computation was illustrated first in this paper. The formation of element stiffness matrix and the solution of the system of linear equations of finite element method (FEM)...
