Advanced laboratory scale model of high phase conversion power transmission line

Theory of high phase order conversion system i.e: six-phase transmission line has proved as an alternative to new line construction or voltage upgrading, the economic and technical viability of three to six phase conversion (termed high phase order conversion) of an existing double circuit line permitting about 73% more energy transmission without any change of the existing line tower, conductors and ROW area. Up to date there are many works done in this SPTL field reductions were only based on digital simulations and calculations. Tests on actual line settings and configuration which are needed during a study are challenges to researchers who have limited access to the lines. It will be more challenging especially reconfiguration exercises for HPO conversion of three phase to six phase system. This paper describes in the development of scaled down six phase transmission line (SPTL) model developed in the IVAT laboratory to serve the purpose of study of the steady state and transient behavior of high phase system.
