“…In case of using individual or multiple nanoparticles techniques inside polymer matrix, power law relationships used in dielectric modeling of composite systems; the composite system have three components (matrix, interphase region and nanoparticles). There are various techniques have been done to make the calculations of the electric field in the three-core belted power cables for determining the stress in cables [31][32][33][34][35][36]. This paper applied the calculations of the electric field in three-core belted cables by using the best charge simulation technique which uses less number of charges and gives small errors and high degree of accuracy achieved [36].…”

This paper presents an investigation on the enhancement of electrical insulations of power cables materials using a new multi-nanoparticles technique. It has been studied the effect of adding specified types and concentrations of nanoparticles to polymeric materials such as XLPE for controlling on electric and dielectric performance. Prediction of effective dielectric constant has been done for the new nanocomposites based on Interphase Power Law (IPL) model. The multi-nanoparticles technique has been succeeded for enhancing electric and dielectric performance of power cables insulation compared with adding individual nanoparticles. Finally, it has been investigated on electric field distribution in the new proposed modern insulations for three-phase core belted power cables.

“…In HV equipment, the electric field can easily be calculated by solving the Laplace's equation with satisfactory boundary conditions, this equation governing the potential distribution in conducting materials and the electrical insulating generally used in HV. In the past years, the CSM was one of the numerical methods mostly used in the calculation of the electric field [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. This numerical application was developed by Steinbigler in 1969.…”

“…Nosseir and Zaky [6,7] proposed a method based on the charge representation technique to compute electric stress in three-core belted cables. Although, their method was later improved by Salama et al [8], the computation error will still be quite significant when the ratio (T/d) of the thickens (T) of core insulation to the conductor diameter (d) is less than 1.0.…”

SummaryThe electric stress inside three-core belted cables is calculated using the charge simulation method combined with the method of imaging. Each conductor is simulated by Nc infinite line charges. An image charge for each fictitious charge is considered to keep the sheath potential at zero. The proposed method has the advantages that the charge values and hence the potential and field stress at any point are expressed as a function of the time wt which result in considerable saving in the computation time. Besides the computation time saving, the proper choice of the values of Nc and the assignment factor fs results in a high accuracy of the potential and field stress. The maximum potential error is shown not to be more than 0.05% and the field deviation angle is not more than 0.11. even when inter-conductor spacing is very small.
