This paper illustrates a charge simulation method based computation of electric potential and field of composite insulators for HVDC lines. The electric field is calculated under both dry and wet conditions and compared to AC line insulators. The results indicate that for the same nominal voltage, the electric field for DC lines is higher than for ac lines, thereby necessitating larger field control...
In high voltage engineering, optimization of electric field distribution is directly related with the design of high voltage electrode surface. Various field optimization techniques are in use and this paper presents a new method based on the biogeographically isolated habitats for the optimization of high voltage electrode surface. This new method is known as Biogeography Based Optimization (BBO)...
A novel numerical strategy of electric field computation based on conventional charge simulation method (CSM) was proposed, according to the geometric feature of vacuum interrupter (VI). The matching relationship of contour points and simulation charges can be conveniently established for different component structure using the proposed geometric feature CSM (GFCSM). For verifying the feasibility...
The electric fields associated with sphere-plane gap geometry is simulated using charge simulation method (CSM). In the present study simulation results with symmetrical placed 6 and 14 point charges are reported. The errors in charge simulation method (CSM) of sphere surface potentials are analyzed by optimally placing the charges. The optimal location of point charges used in simulation are identified...
