Utility-based economic assessment of distribution transformers considering specific load characteristics and environmental factors

摘要

Due to the large number of installed distribution transformers in power systems, there is a considerable potential for energy savings through investment in low loss transformers. This paper investigates different methodologies for the economic assessment of distribution transformers taking into account the detailed load characteristics that affect their life cycle cost. The analysis is conducted from the electric utility point of view, using the total owning cost formula and introducing built-in environmental factors.
