New selection method reduces conductor losses
A new method to determine the economics of conductor sizing on distribution feeders is described. Three factors must be considered: (1) investment cost; (2) energy cost; and (3) demand cost. It is necessary to consider not only the initial investment cost of a distribution feeder being installed for an anticipated peak feeder loading, but also some hidden costs. These hidden costs include the cost of energy lost due to l/sup 2/R losses in the conductors, and the additional system capacity required to supply those energy losses. Therefore, the actual cost of a distribution feeder includes the initial investment cost, the energy cost of losses, and the demand cost of losses. Because costs change every year, these costs must be considered on an annual basis over the life of the feeder.
