| Abstract | An over-voltage online monitoring system based on the impulse full current of arrester is developed in this paper. The system measures the wave head and amplitude of the impulse full current of arrester through external-integral rogowski coil, and transfers the measurement result to the upper computer via USB optical measuring system, and then implements the measurement and monitoring on over-voltage through function fitting software. This paper focus on the over-voltage fitting method based on the impulse full current of arrester, and achieves amplitude sample database of impulse current, amplitude of wave head and node voltage (residual voltage) by node voltage test and simulation of wave head and amplitude in different lightning and switching impulse action current, and obtains the impulse current and node voltage fitting algorithm according to mass of data, as well as compiles recovery software of impulse current-node voltage by use of Visual Basic to implement reduction of over-voltage amplitude. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
