Evaluation of the Cost of Losses for Underground Transmission Cable Systems

This paper discusses issues related to the evaluation of cost of losses for underground power transmission cable systems. The first section of this paper reviews the need for cable system cost of losses evaluation. Cable characteristics, utility system issues, and economic factors relevant to the evaluation of losses are then presented and aspects which might have a significant effect on loss evaluation are highlighted. Currently used evaluation methods are briefly reviewed and the "present worth of annual revenue requirements" evaluation method is presented in more detail. Final discussion considers how much detail is required in a cost of losses evaluation and how the cost of losses information can be used.
