| Abstract | A novel method that integrates fiber technology with support vector machine classifiers to detect the contamination grades of high voltage insulators is presented i n this paper. Based on laboratory simulation experiments of the contaminated silex sensor and insulator, under condition of the complicated nonlinear relationship between the luminous flux attenuation, the contamination grades of insulator, the environment humidity and ash density, the least squares support vector machine (LSSVM) pattern recognition model of detection of the contamination grades is constructed by means of particle swarm optimization (PSO) arithmetic to optimize the parameters of the model. The method takes advantages of the minimum structure risk of SVM and the quickly globally optimizing ability of particle swarm, and the mapping relation between the luminous flux attenuation, the environment humidity, ash density and contamination grades is built quickly by learning from sample data. Then the contamination grade of insulator online detecting system is developed based on the fiber technology. And the application effect proved the feasibility of the method. |

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.
