| Abstract | This paper describes Amorphous Metal core Distribution Transformers (AMDT) and its potential to obtain economic and environmental benefits when pre-existing transformers are to be replaced. Vattenfall's ambition is to decrease losses within the Vattenfall Group's distribution network, thus contributing to the environment and economy, and hence confirm that this is an important issue for Vattenfall. Distribution transformers within the Vattenfall Group's distribution network in Sweden, Germany and Poland are investigated and presented in three different business cases that consider the current sizes, quantities, ages and load utilization. The inventory of the distribution transformers used at Vattenfall, indicates that conventional transformers of fairly high loss types have been selected over low loss types. Choosing low loss amorphous transformers when pre-existing transformers are to be replaced, means that the CO2 emission will be significantly reduced. AMDT have the potential to reduce transformer no-load losses by up to 70% compared to conventional technology. This paper discusses the general aspects of AMDT transformer losses as well as the importance of using the Total Ownership Cost (TOC) method to determine the economic benefits whenever a unit is to be purchased. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
