Surface Effect on Three Phase Lines of Low-Ohmic Furnaces

The article another option of using numerical method of elementary conductors in surface effect three-phase supply linesfor low-ohmic furnaces. Impedance asymmetry of three-phase supply lines of different conductor profiles and various spaceconfigurations is analysed following to the author`s article published in this journal (Vol. 2/2003, No. 2, pg. 42). Options of reducingunfavourable effect of so called live and dead phase and their utilization in design and construction of mentioned lines are outlined.
