Abstract

outward vector to Z, c = A/4n where A is the solid angle under which the point P sees the oriented surface Z and E, is the relative permittivity of 51.

Measurement and simulation of the voltage distribution and the electric field on a glass insulator string

“…As a result, there is a significant decrease in the electric field strength at the region of glass. This decrease is also confirmed by [2].…”

“…Numerical methods can be divided into two groups. The first group consists of the charge simulation method and the boundary element method [2]. These two methods are preferable for open boundary problems, such as insulators or power lines.…”

Simulation of the potential and electric field distribution on high voltage insulator using the finite element method

“…The electric field and potential distribution can be estimated using various numerical techniques, such as Charge Simulation Method (CSM), Finite Difference Method (FDM), Boundary Element Method (BEM) and Finite Element Method (FEM). In the field of high voltage transmission line applications, the published results of the numerical simulation of the potential distribution and the electric field of some studies are all for simple geometries [17][18][19][20][21][22]. A numerical simulation is an approach that gives researchers the possibility to analyze the behavior of several phenomena which, because of their complexity, are beyond the scope of classical calculus [16].…”

Measurement and simulation of the electric field of high voltage suspension insulators

“…Several methods such as finite difference method [3], boundary element method [4][5][6] and finite element method [7][8][9][10][11][12][13] have been developed for the computation of electric fields and potentials along an insulator string. The simulation methods give the possibility to examine the behaviour of models with very complex geometry without using analytical methods or experiments.…”
