The financial implications of losses in transmission and distribution line conductors are analysed, with the introduction of two new universal parameters, viz. Financial Burden Constant (FBC) and Critical Operating Hours (COH). Each size of a transmission line conductor has a distinctive value of FBC and COH. Techno-economic issues related to transmission systems can very conveniently be addressed using these parameters. The uniqueness of these two constants lies in their ability to combine all the techno-commercial parameters associated with transmission lines and to assist in the comparison of all techno-economic issues from a global perspective. The paper demonstrates how the design and the selection, operation and renovation of the transmission line conductors can be carried out straightforwardly with the help of FBC and COH. These parameters form convenient and simple tools for evaluating transmission and distribution line projects and operating on a global platform.
