In this presentation, the impact of three different insulation systems on the total life cycle carbon emissions of a 40/60 MVA, 132/33 kV ONAN/ONAF transformer is analyzed. The study compares two designs based on a conventional insulation system (for mineral oil or natural ester) with a semi-hybrid insulation system (as high-temperature insulation in combination with natural ester) for the scenario of operating the transformer in lower carbon electricity grids and economic and environmental benefits of such high-temperature insulations compared to conventional designs.
