| Abstract | Due to enduring more disturbance such as environment varieties and surveying interference and information transmission mistakes as well as arisen error while processing data in surveying and monitoring state information of transformer, thus uncertain and incomplete information and ill data may be produced. So the study how to apply these data to achieve the approving effect is a very significant job for fault diagnosis of transformer. Moreover, real time is another important characteristic so as to meet high-speed diagnosis requirements. Based on points, a fuzzy neural classifier is proposed based on rough sets theory in this paper, the method firstly considers all sorts of gas capacities in transformer oil to form Rogers ratio diagnosis table, then rough sets is applied to implement attributes reduction and a simplified decision table is got, fuzzy algorithm with Gauss subjection function makes attribute values fuzzy, afterwards, fuzzy attributes are connected to input neurons of neural classifier to make patterns classified, finally, a fuzzy neural classifier is formed for fault diagnosis for transformer. The practical results show the approach can effectively minimize the problem-solving scale and improve real time properties, and owns high anti-inference capabilities, and is an effective method for fault diagnosis of transformer |

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.
