Electric field modelling of non–Ceramic high voltage insulators [PDF]
Australian Journal of Electrical and Electronics Engineering, 2008 This paper applies a three-dimensional (3D) electric field analysis program to calculate the field distribution at the live end of 110 kV non-ceramic insulators used in the Queensland transmission system. A number of 110 kV insulator configurations have been modelled, including a post, a longrod and a horizontal vee assembly, to determine the electric ...
