Transmission lines are used for transportation of energy from the point of generation to the point of usage. A transmission line may be single-core conductor or stranded conductor. Stranding reduces line reactance, skin effect and the tendency of occurrence of corona effect. Transmission line parameters such as inductance and capacitance depend on the geometric mean radius (GMR) of the line. GMR is essential for Voltage and Voltage-Drop analysis which is necessary to ensure save operation of power system. Arithmetic and logical models of triangular, hexagonal, circular and sector shaped stranded conductors are presented. The models which accurately predict the Cartesian coordinates of centers of strands are coded into computer programs which facilitate both the accurate graphical drawing and accurate computation of GMR of stranded conductors.

Abstract
Transmission lines are used for transportation of energy from the point of generation to the point of usage. A transmission line may be single-core conductor or stranded conductor. Stranding reduces line reactance, skin effect and the tendency of occurrence of corona effect. Transmission line parameters such as inductance and capacitance depend on the geometric mean radius (GMR) of the line. GMR is essential for Voltage and Voltage-Drop analysis which is necessary to ensure save operation of power system. Arithmetic and logical models of triangular, hexagonal, circular and sector shaped stranded conductors are presented. The models which accurately predict the Cartesian coordinates of centers of strands are coded into computer programs which facilitate both the accurate graphical drawing and accurate computation of GMR of stranded conductors.
Author Keywords: Power Transmission, Stranded Conductors, Geometric Mean Radius, Line Parameters, Electric Field, Magnetic Field, Geometry.
