Abstract

This chapter gives a brief overview of some of the important bare conductors available for use on overhead power lines. The basic principles applicable to the optimal selection of conductor size are discussed. This chapter also presents a novel procedure, formulated to optimise the selection of the conductor and tower configuration from the point of view of an overall system. The procedure highlights the significance of incorporating in the optimisation algorithm the following factors: planning and load forecast considerations, power quality constraints, voltage collapse studies, line performance studies, corona and audible noise, induction and transposition studies, and life-cycle cost of maintenance for the different options. The methodology and results of a case study are presented to demonstrate the proposed procedure.
