| Summary: | In this paper we present an approximate analysis of the proximity effect in a
shielded symmetrical three-phase line with conductors of circular cross
section. The system of two integral equations for current densities is solved
approximately by assuming them in the form of two finite series with properly
chosen basic functions. The unknown coefficients in these series are found by
applying the point matching procedure. Numerical results are given for the AC
to DC resistance ratio of the line conductors and for the power loss in the
shield. |
