The place of generation of technologic heat is important applied criteria for classification of electric heating. According to that, the direct heating is if the heat is generated directly in the heated material, or the indirect heating if material is heated indirectly by the heat generated in conversion element. Possibilities of practical application of both methods are typical for resistant heating...
This article deals with another exhibition of possible using numerical method of elementary conductors. It is applied in the course of analyze impedance relations of one and three phases supply lines to low-ohmic furnaces, in configurations of single and bundled lines. Results of analysis can be used for cross section form optimalisation and spatial configuration of objective supply lines. Optimalisation...
This article presents possibilities of practical application of numerical elementary conductors method for investigation of surface effects. Their influence on elements of conductor impedance result from of intensive electromagnetic fields action in the conductor surroundings. The method particuralry applies to calculation of skin effect and proximity effect coefficients m different shape conductors...
