Abstract | In this work a current transformer (CT) with toroidal core is analyzed from the viewpoint of the eccentricity of the primary circuit where one conductor goes through the core's window and the other is outside the core. The research is focused on the influence of the position of the primary circuit conductors on the evaluation of the mutual inductance between the primary circuit and the secondary winding-an influential factor on the CT's amplitude error. Purely analytical results and closed-form expressions for the mutual inductance are obtained when the core is made of a nonmagnetic material. A finite-element method is also utilized for the numerical computation of the mutual inductance, for nonmagnetic and ferromagnetic cores. Results are cross-validated using both methods. Results are presented and discussed taking into account the system geometry and the number of turns of the secondary winding. This novel contribution shows that the response of nonmagnetic-core current transformers can be significantly affected by the positional eccentricity of the primary circuit, especially when the secondary winding does not possess a large number of turns. |

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.
