| Abstract |
In this study electromagnetic fields near electric power lines were derived by dipole antenna theory and electromagnetic fields near 3 phase power lines with vertical configurations were formulated and could be computed easily using these formula. It seems that those formula could be applicable to the consideration of electromagnetic fields during the design of transmission and distribution lines. Those formulated equations on elements of electromagnetic fields were applied to the model of a transmission-line system and were calculated by Matlab programs. The calculation results are follows. For variation of horizontal distance profiles of Ey and Bz are same each other, and also those of By and Ez are same each other. This means that coupled elements of E and B are perpendicular each other and have the propagation direction of the right-hand system such as x→Ey→Bz. Resultant electric field E is dominated by the element Ey and resultant magnetic field B is dominated by the element Bz. |
