Charge Simulation Method with Complex Fictitious Charges for Calculating Capacitive-Resistive Fields

Efficiency of different optimisation approaches for optimal parameters of the CSM for investigating the onset field due to corona point

“…Numerical simulation methods are categorised according to the domain and equations used into two types [1]. The first type is open domain methods that use integral equations, and they include the charge simulation method (CSM), moment method and boundary element method [1,[8][9][10][11]. The second type is bounded domain methods that use differential equations, and they include the Monte Carlo method and finite element method [1,[8][9][10][11].…”

“…CSM is an open domain technique that provides the calculations without any limiting restrictions or boundaries for using only one dielectric medium [1,4,[8][9][10][11]13]. Also, CSM is used for complicated multi-dielectric systems, three-dimensional (3D) fields, space charge modified fields and electrode and insulator contour optimisations so, it is considered the best effective method in complex calculations.…”

“…In this research, CSM is chosen in operating study calculations with image technique method. Although the unique behaviour of CSM, it suffers from the complicated determination of the initial location, optimum size and arrangement of simulated fictitious charges that simulate the needle electrode and help in describing the electric field and potential expressions [1,8,10].…”

A Comparative Study of Electric Fields beneath Compact and Non-Compact Transmission Lines

“…For a.c. transmission lines the charges are assumed to be complex. 8 Therefore, the electric field at the ground level is a vector sum of the field strength due to the phase charges at the surfaces of the conductors and their images.…”
