Abstract :
In many analyses of line parameters, approximations ignoring eddy currents in conductors can be used. But, in close conductors, the AC parameters vary greatly with frequency and conductor spacing. For some configurations, the increase in resistance due to skin and proximity effects can be in excess of 100% compared to skin effect resistance alone. The present paper deals with the analytical calculation of per unit length impedances of closely parallel multiwire lines in a frequency range covering [0 Hz, 5 MHz]
