Abstract

The article presents the calculation of electric fields in the 10 kV high-voltage RM-6 cell monoblock to determine the optimal placement of electric field intensity sensors. The cell single-phase, two-phase, and three-phase operating modes are studied for considering various configurations of electric field intensity distributions within the monoblock. Numerical methods suitable for field intensity calculation with taking into account the complexity of power frequency electric field configurations are considered, including the finite difference method, finite element method, integral equation methods, and equivalent charges method. The main advantages and shortcomings of each method are pointed out. The newly developed 3D model of the RM-6 cell monoblock is described, including the way in which it takes into account the cell configuration, materials used, dimensions, and boundary conditions approached to the operational conditions. The model applicability is substantiated. The obtained electric field intensities at various points within the monoblock are compared with the allowable ranges specified in regulatory technical documentation. The field intensities within the insulation volume are analyzed to determine the required number and placement of electric field intensity sensors. The cell design optimization versions are proposed.
