| Abstract | This paper aims at the comparison of the Electrostatic Charging Tendency (ECT) of mineral, vegetable and synthetic oils using a spinning disk system (CIGRE Cell) covered on its both sides with different types of pressboards and papers. The ECT of insulating oils generated by the charge concentration gradient at the oil - pressboard/paper interfaces are analyzed in function of the rotating speed of the disk. It is shown that the generated charge is slightly higher with vegetable oil than that with mineral and synthetic ester oils. This may be due to differences in the molecular structures of these oils, whose interaction with the pressboard/paper is different; the phenomena occurring at the double-layer (interface) are not identical. However, the differences observed do not constitute an obstacle to the use of vegetable oil as a substitute for mineral or synthetic oils, with respect to the problems and risks associated with static electrification phenomena. |

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.
