Capacitive-resistive field computat

Capacitive-resistive field computations are carried out around post-type HV insulators of varyingshapes. Thc boundary clcment method (UEM) has bccn employed for clcctric field coinyutations.Different insulator shapes havc bccn obtained by varying scvcrd parameters, whichdefinc the shape of the HV insulator contour. For each insulator shape, tlic maximum stressoccurring on the insulator surfacc has been dctcrmined with no surface pollution, uniformsurface pollution and also partial surface pollution. For partial pollution, scvcral cases havcbccn studied, in which differcnt sections of the insulator surface are pollutcd. Furthennorc,thc cffect of elcctrode radius on the maximuin stress on insulator surface bas been investigatcd.The results obtained are presented in this paper in dctail.
