The current study was conducted by making a series of experimental measurements of the electric field strength E. The obtained results have been interpreted using the method of mathematical modelling because the object of study – electromagnetic environment (EME) is a multifactorial system. With the accepted limitation of considering the influence of only two factors (frequency and time intervals) a two-factor regression analysis was used. The processing of the obtained data was performed by two-dimensional quadratic objective function.

“…Mukherjee and Roy carried out capacitive field calculation in a capacitor bushing [5] as well as in a porcelain bushing [6] by the charge simulation method [7]. Okubo et al [8] reported capacitive field analysis of HV bushings by a combination method, involving charge simulation and finite element method. Capacitive-resistive field calculation including surface resistance for a simple bushing configuration by finite element method was done by Andersen [9].…”

Capacitive-resistive field distributions including surface and volume resistivities have been computed in and around HV porcelain and capacitor bushings. The boundary element method has been applied for field computation in two axi-symmetric bushing configurations including four dielectrics. Effects of uniform and non-uniform distributions of surface resistivity and volume resistivities of different dielectric media are studied in detail. Special emphasis has been given to the stress distributions along the various dielectric-dielectric boundaries. Further, the values and locations of maximum stresses in different dielectrics are determined and reported in this paper. The plots of equipotential lines for a few typical cases of field distributions are also presented here for both bushings.

“…Recently, numerical methods for the electric field calculation have been extensivety developed [ 1 -121 and it became possible to solve theoretically even a space charge [3] or a leakage current field [7], for both two-dimensional and mi-symmetric fields. In addition, applications of electric field analyses are also remarkably expanded in high-voltage and insulation design fields.…”

This paper describes the development of three‐dimensional electric field analysis by using segment method which enables to calculate the electric field with high accuracy and with enhanced efficiency. In the segment method, an electrode configuration of high voltage apparatus is simulated by arrangement of several kinds of small components which are defined as segments. In the calculation, a charge simulation method is used. In this paper, the fundamental construction and arrangement parameter of segments are described. On the basis of the application results, the calculation accuracy is discussed.
