Electric field modelling of non–Ceramic high voltage insulators [PDF]

open access: yesAustralian 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 ...

Electric Field Analysis of High Voltage Insulators

open access: yesInternational Journal of Computer Science and Informatics, 2012
This paper involves designing and applying electric field analysis on multiple long rod insulators. Quality HV insulators are an integral part of power systems because they separate the Transmission lines carrying high voltages from the grounded poles. They must have the ability to withstand both high electrical and mechanical stress.
