| Abstract | In high voltage apparatus, for example GIS, partial discharge (PD) can occur because of impure particles showing up, especially, some kinds of metallic particles appearing during service. The PD failures are dangerous and detrimental for the GIS, because they could destroy the insulating system of the high voltage apparatus, resulting in a great deal of economic damage and personal safety issues. So the diagnosis, monitoring and prediction of the PD failures are of concern for electrical engineers. Experiments have been made for simulation of the GIS structure and condition service under different kinds of applied voltage and existance of many sorts of metallic particles which possess variable materials (for instance, copper, stainless steel, steel and so on) in different diameters, lengths and geometry configurations. Through the practical experiments in the laboratory the relationships between inception voltage of PD, PD quantity, length, materials and geometry have been obtained. Meanwhile the PD signals have been recorded by the measurement systems. The position of the particles located shows different waveform and behavior, so that it could supply a way to detect the PD failure characteristics, location and attributes, and it helps analysis, judgement and assessment of the service conditions. The recognition system of PD pattern has been designed for recognizing PD failures according to artificial neural network. experiments and practices demonstrate that the method is very useful and effective. |

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.
