    Opis:
    This paper presents an analytical method for determining the power losses in the three-phase gas-insulated transmission line (i.e., high-current busduct) of circular cross-section geometry. The mathematical model takes into account the skin effect and the proximity effects, as well as the complete electromagnetic coupling between phase conductors and enclosures (i.e., screens). Apart from analytical calculation, computer simulations for high-current busduct system power losses were also performed with the aid of the commercial FEMM software, using two-dimensional finite elements.

    Opis:
    This paper presents an analytical method for determining the power losses in the three–phase gas–insulated line (i.e., high-current busduct) of circular cross–section geometry which phase conductors are placed in vertex of a square. The mathematical model takes into account the skin effect and the proximity effects, as well as the complete electromagnetic coupling between phase conductors and enclosures (i.e., screens). The power losses produced by high-current busducts are usually calculated numerically with the use of a computer. However, the analytical calculation of the power losses is preferable, because it results in a mathematical expression for showing its dependences on various parameters of the line arrangement. Moreover, knowledge of the relations between electrodynamics and constructional parameters is necessary in the optimization construction process of the high-current busducts.
