The conductor configuration of a bundled single-phase overhead transmission line is shown in Figure Line X has its three conductors situated at the corners of an equilateral triangle with 10-cm spacing. Line Y has its three conductors arranged in a horizontal configuration with 10-cm spacing. All conductors are identical, solid- cylindrical conductors, each with a radius of 2 cm. (a) Find the equivalent representa- tion in terms of the geometric mean radius of each bundle and a separation that is the geometric mean distance. Line X 10 cm 6 m Line Y 10 cm 10 cm
