Comparison of the ecoprofiles of superconducting and conventional 25 MVA transformers using life cycle assessment methodology

MVA transformers using life cycle assessment methodology Renza Berti*, Franco Barberis*, Valerio Rossi*, Luciano Martini* CIRED 2009 20th International Conference and Exhibition on ELECTRICITY DISTRIBUTION Praga, 8-11 Giugno 2009 * ERSE SpA (EX CESI RICERCA) A Life Cycle Assessment (LCA) study, according to ISO 14040 Standards, was carried out with the aim to compare the environmental performances of three 25 MVA transformers with different manufacturing characteristics: • high temperature superconducting (HTS) transformer with first generation (1G) BSCCO tape windings, • HTS transformer with second generation (2G) YBCO coated conductors windings, • conventional paper-oil insulated transformer with copper windings. A “from cradle to grave” approach was used for the comparative LCA. This paper reports the results of LCA with the identification of the most environmental-friendly solution and of the critical issues in the environmental profiles for the three different types of power transformers
