Abstract

The article presents examples of advanced material solutions that are available today to transformer designers. If properly applied, these solutions can be successfully used for transformer cost reduction.In the presented examples the cost optimized transformers could be designed for ability to withstand high overloads and thus their long-term performance and reliability could be improved. This article also presents studies showing the possibility of design optimization for transformers with ester liquids, independent from overload requirements. Example results show that in certain specific cases the cost of a transformer filled with ester liquids can be reduced by a proper combination of high temperature insulating materials, both solid and liquid.
