| Abstract | At present, the main parameter is the "ultraviolet flare area" and "flare diameter", in order to has a contrast in the insulator for fault diagnosis, in this paper, through the water spray classification method to choice normal, good, a mark, degradation and serious aging 5 kinds of insulation of the same kind of insulator. The platform structures is in the laboratory, the pressurized are 8 kV, 10 kV and 15 kV, through the South Africa CoroCAM504 UV camera to take enough UV insulator pictures under discharge conditions, using digital image processing algorithm extracting the two parameters, through MATLAB digital simulation, paper obtain the change of two parameters with insulating of state trend. The results show that: 1) when the insulator insulation is in good condition, flare area and flare diameter almost negligible, correspondence is better, conversely, in these two parameters are small, it's always good insulator insulation. 2) when the insulator insulation comes problems, both had a tendency to rise, but flare area have a turning point "4", and flare diameter not, this shows that when insulation degradation to certain degree, flare area is not too big, and differentiate the spot diameter can be distinguished. Ultimately it provides a quantitative assessment of the basis and certain guidance for insulator in the running status. |

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.
