| Abstract | The life span of the transformer is mainly decided by its solid insulation, especially insulation paper (pressboard). In order to analyze the ageing mechanism of power transformer insulation paper, we use the atomic force microscope (AFM), which is one of the important instruments in nanometer area to observe the surface of thermal aging insulation paper. Through the comparison of some specimens' AFM figures, we discovered that the molecular arrangement of the initial cellulose paper is close and ordered, some of the hexagonal mesh structures of the D-glucopyranose units were broken down after a few weeks accelerated thermal aging. Then we analyzed the micro mechanism of the aging process and the influence to the insulation paper caused by thermal aging. Some methods to improve the dielectric properties of insulation paper are also included |

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.
