Szukana fraza: [Abstrakt = "Design of the high\-current busducts on high currents and voltages causes necessity precise describing of electromagnetic and thermal effects. Moreover, knowledge of the relations between electrodynamics and constructional parameters is necessary in the optimization construction process of the high\-current busducts. Information about distribution current density and power losses is a base into analysis of electrodynamics and thermal effects in the high\-current busducts. This paper presents an analysis of the temperature in the flat three\-phase high\-current busduct. Calculations of the current density in the phase conductors were made by analytical method, but the temperature was determined by finite difference method. The mathematical model takes into account the skin effect and the proximity effects."]
