Effects of Amorphous Core Distribution Transformers in Improvement the functioning of the Electricity Distribution System)

This paper describes Amorphous Metal core Distribution Transformers (AMDT) and itspotential to obtain economic and environmental benefits when pre-existing transformers are to be replaced.The inventory of the distribution transformers indicates that conventional transformers of fairly high losstypes have been selected over low loss types. Choosing low loss amorphous transformers when pre-existingtransformers are to be replaced, means that the emission will be significantly reduced. AMDT have thepotential to reduce transformer no-load losses by up to 70% compared to conventional technology. TheAMDT option helps to reach efficiency requirements easily and economically. Lastly, lower losses indistribution transformers will decrease demands on primary energy production, reducing the demand onfossil fuels.
