Abstract :
This paper describes degree of uniformity and electric field intensity in the gap between two electrodes subjected to high voltage which is necessary to study the behavior of insulation for design of high voltage equipments. Here, 3-D arrangements of fictitious charges and contour points in Cartesian co-ordinates are considered to find out the desired outputs for Sphere-Sphere and Sphere-Plane electrodes by using well known Charge Simulation Method (CSM), using MATLAB. Both the symmetrical and asymmetrical applied voltages are considered for the investigation. From this investigation it is revealed that more uniform electric field having degree of uniformity of η=0.5507 and 0.4394 has been obtained for symmetrical applied voltage of Sphare-Sphare and Sphare-Plane respectively, compared to η=0.3699 and 0.3428 for asymmetrically applied voltage. It is also found that the probability of insulation breakdown is greater near the High Voltage electrode compared to other portion of the dielectric. The developed computer program can be used in designing HV equipments.
