| Abstract | This paper describes the calibration of a Rogowski coil (RC) with an integrator assigned for current measurement in the range up to 25 kA at 50 Hz mains frequency. A current loop with 10 turns with a current of 2.5 kA is used for calibration. The magnetic field generated in such a way differs from the field of one turn placed in the centre and passed with a current of 25 kA. The influence of non-homogeneities of winding and the cross-section of the RC may cause a calibration error when using a current loop. The difference in the results between using a current loop and one turn and the measurement uncertainties are given below. |

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.
