| Abstract | Transformer is one of the most important and vital components in the power system. Distribution transformer with iron-based amorphous metal core is an energy efficient transformer. Core loss from that type of transformer is approximately 25-30% less than conventional type of cold rolled grain oriented silicon steel core (CRGO), namely amorphous core can slash the no-load losses by up to 70% and make possible to build very high efficiency distribution transformer. To reduce the losses of transformer means to contribute to decrease greenhouse gas emissions by reducing the production of energy loss. In EU network are about 5 millon distribution transformers and contributing approximately 30 million tons of $CO_{2}$ emissions. There are more than 2,5 million amorphous metal core distribution transformers (AMDT) in worldwide operations. This paper introduces a brief comparison between conventional distribution transformers and amorphous core distribution transformers. Investigation is carried out on the iron-based amorphous wound core distribution transformer production technology. Amorphous ribbon is relatively thin (22-30 μm), hard, stress-sensitive and requires annealing process under a magnetic field to achieve the optimum performance. Result from that the eddy current losses lower as compared to CRGO and ease of magnetization and demagnetization, also lower hysteresis losses. A case study is presented capitalized losses and the payback period over the lifetime. The evaluation states the difference between AMDT and conventional transformers with CRGO. |

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.
