| Abstract | The study of the partial discharge (PD) activities allows to highlight the ageing stage in the insulation material under test. During the life of the insulating material, the shape of PD signal changes relating to the ageing stage. This paper proposes an analysis on a dielectric system, affected by partial discharge activities, based on an original processing of the acquired data. This approach allows to minimise the necessary classification data. In what follows the basic steps of this approach are reported: data acquisition; identification of the significant parameters using wavelet transformed signal; fuzzy processing of the data. The main results presented in this paper are: a full automatic process; a diagnostic index of the phenomenon trend; if is possible to consider this index as a way to monitor dielectric behaviour. A short description of the phenomena, together with an introduction to wavelet and fuzzy logic are reported too. |

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.
