Abstract :
The numerical results detailed in this paper reflect on a method proposed to accurately appraise the energy and the demand component of the cost of losses for evaluating the total ownership cost of power transformers. Specifically, the proposed method is evaluated on a small-scale real system, by incorporating realistic financial data and system characteristics through appropriate technoeconomic models as well as statistical evaluations. The calculated loss components of this paper are compared to the methodology detailed in IEEE C.57.120-1991.
