MODERN TRENDS IN THE ELECTRICAL DESIGN OF TRANSMISSION LINES

Abstract

In this dissertation a discussion of the recent developments and studies in the, field of the electrical design of the modern transmission systems has been carried out. Both the old and new design methods for fi ng insulation levels for linos and sub•Stations are discussed. Also studies have been carried out to bring out the reductions possible In the insulation levels of transmission lines and sub-station equipment to effect substantial econo ies. bbr the purposes of Illustration typical 220 K.V. and 132 K.V. transainsIon systoles have been chosen. Reduced insulation levels for the sane are recomracnc ed. The possibility and dosireability of uprating the existing 132 K, V. lines in India tao 220 K.V. has been brought out in order to enhance their power carrying capabilities at nominal costs.
