Abstract | Iron loss models of electrical steel sheets and magnetic cores are of importance in multiple areas of physics and engineering. Next to the development of new materials a good understanding of the physical effects of magnetization and loss contribution is an additional basis for design optimization of electrical machines for example [1, 2]. This paper, however, discusses the application of analytical loss models in the area of transformer diagnostics on a low frequency data basis. As core data and the flux density at the operating point of the transformers are not available, the model proposed is optimized to work with these restrictions. Currently iron losses are divided depending on their origin into hysteresis, classical eddy current and excess losses [4]. Although this loss interpretation is very accurate this model only divides the total losses in static and dynamic loss components. The model is optimized for engineering purposes to be operated with low testing frequencies and low voltages. |

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.
