Abstract—In this paper, an attempt has been made to enhance the loading of radial distribution by selection of proper conductor. The critical values of total real power load (TPL) and total reactive power load (TQL) for constant power are derived out for the sub-station voltage of 1.0 pu. for 69-node radial distribution network. The proposed method will reduce the real and reactive power losses, improves voltage profile and enhances the loading capability of distribution network. The voltage deviation is reduced to ±10%.The superiority of the proposed method has been established by ±6% from ±10% taking results iteratively. Using network reconfiguration, loading is further increased.
