| Abstract | The ability to accurately characterize the partial discharge events in switchgear systems can help to prevent effectively the breakdown of the system. In this work the electromagnetic radiation spectrum from partial discharge is investigated in the entire structure of medium voltage switchgear (Type D24-121114 of Driescher). The components of the switchgear simulated include voltage and current transformers, terminal studs, fuses, earthing switches, connection parts and the metallic enclosure. Finite Element Method has been used in this work. The partial discharge is situated on the surface of insulators being modeled by a Gaussian pulse. The intensity of the electromagnetic field which propagates from partial discharge is influenced by the switchgear components. The work shows that by analyzing the radiation spectra caused by partial discharge in a switchgear system the positioning of the electromagnetic sensors for fault detection can be optimized. |

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.
