| Abstract | A novel test method for the assessment of the bulk dielectric properties of oil-paper insulation has been developed. Specifically, the authors describe a simple on-site DC testing and apparatus for the determination of the polarization spectrum in the polarization time-constant domain of 10/sup -3/ to 10/sup 4/ s. In this range the so-called interface polarization phenomena of long time constant are active, which are highly influenced by the water content of oil-impregnated paper insulation and the adsorption of byproducts of aging. The method can be regarded as a complementary diagnosis method of dissolved gas analysis and other analytical methods and gives information on the general state and dielectric aging of the impregnated paper insulation. The test method and apparatus have been successfully and widely used on high-voltage power transformers of the Hungarian Electricity Board. |

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.
