Comparative life cycle assessment of a MV/LV transformer with an amorphous metal core and a MV/LV transformer with a grain-oriented magnetic silicon steel core

DOI: 10.1049/cp.2009.0958 ISBN: 978 1 84919 126 5 Location: Prague, Czech Republic Conference date: 8-11 June 2009 Format: PDF The life cycle assessment methodology, according to iso 14040 standards, was applied to an amorphous metal core transformer and a transformer with a high permeability grain-oriented steel core, rated at 250 kVA. The aim was to evaluate and to compare the environmental performance of the two transformers, and to identify the more environmental-friendly solution. A "from cradle to grave" approach was used considering the main phases of production, transportation, use and end-of-life management of the two transformers. In this paper the main results of the assessment are presented and discussed.
