  author={Tulsee Doshi and R. S. Gorur and Jim Hunt},
  journal={IEEE Transactions on Dielectrics and Electrical Insulation},
Satisfactory operation of composite insulators is intimately related to the surface electric field (stress) distribution. This paper presents results of calculation of the electric field distribution for composite insulators up to 1200 kV, using a 3D software package based on the Boundary Element Method. The impact of corona and grading rings, single and bundled conductors, insulator orientation (dead-end and suspension), single and double units, and surface condition (dry and wet) on the… CONTINUE READING
