Opis:: Work has shown how a reverse reaction magnetic field influences the whole magnetic field within the conductor and its vicinity. A description of this is presented in formulae for relative field values and parameters taking into account frequency, conductivity and diameter of the conductor. This has shown the field to be an elliptical field.

Opis:: This paper presents an analytical method for determining the magnetic field 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 magnetic field were also performed with the aid of the commercial FEMM software, using two–dimensional finite elements.

Tematy:: magnetic field
rectangular busbar
high-current busduct
Opis:: The paper presents the results of the calculations of the magnetic field for the both shielded and non-shielded 3-phase MR 250 busbar manufactured by Elektromontaż 2 in Katowice, Poland. The busbar magnetic field has been determined by the following methods: analytical method for non–shielded busbar without taking into account the skin and proximity effects, analytical–numerical method based on integral equations, two-dimensional method of finite elements with the use of the commercial FEMM software, measurement method on a test stand. The measurements were performed with the use of a special non-directional magnetic field meter. A satisfactory compliance of the calculations has been obtained.

Opis:: In the paper shown the impact of the screen thickness on the total magnetic field of a double-pole bifilar line in the screen and its immediate vicinity. The resultant magnetic field in the high-current busduct of this type has two components of different amplitudes and initial phases. As a consequence this field is elliptical. This phenomenon has been described with the formulas relevant to the relative values of the field and the parameters allowing the frequency, conductivity, and the cross-section dimensions of screen. Into account was taken skin, internal and external proximity effects. These phenomena have a strong impact on the magnetic field in the environment of two-conductor shielded highcurrent busduct and should be taken into consideration also for the industrial frequency of phase currents.

Opis:: In the paper discusses the influence of grounding or shorting of the screen on the magnetic field of screened phase conductor. This phenomenon has been described with the formulas relevant to the relative values of the field and the parameters allowing the frequency, conductivity, and the cross-section dimensions of screen. Into account was taken skin, internal and external proximity effects. Components of this field were expressed through modified Bessel’s functions as a function r and & of cylindrical coordinates. As a consequence this the magnetic field is a rotating elliptical field.
