| Abstract | Aiming at the subjective limitations of the traditional condition monitoring and evaluation methods for the power transformer, the condition assessment method of the transformer state based on the dynamic gray target theory is used to evaluate and diagnose the operating condition and the fault mode of the transformer. The probabilistic reasoning mechanism based on the distance measurement is constructed, and the electrical testing data and the oil chromatography analysis data are fused. That improves the credibility of the transformer's condition evaluation and fault diagnosis. The transformer's condition assessment simulation system is developed to achieve the measurement control of the transformer's partial discharge, the measurement control of the core's grounding current, the measurement control of the gas and micro-water in oil, and the measurement control of the oil temperature. On this basis, the evaluation results can accurately reflect the health state in the functional units of the transformer and the overall, so as to predict and prevent the faults, arrange reasonably the maintenance planning and focus. |

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.
