| Abstract | Recently has been submitted for publication the revision of IEC 60296, which concerns specification for unused mineral oils to be employed in switchgear and transformers. For the transformers, the IEC 60296 Standard, in comparison with the past Edition, introduces oils with a reduced viscosity having obviously also a decreased flash point. At the same time a new Standard (Project IEC 60076) is now under development, actually in circulation as Committee Draft: "Guide for design and application of liquid-immersed power transformers using high-temperature insulation materials". This Guide, among others, include also mineral oils (called HTM-240 and HTM-205) having a much higher flash points, up to 240/spl deg/C, accompanied with acceptable increases in their viscosities. It seems to be a very interesting point to investigate how change the electrical properties of these new mineral oils having increased and reduced viscosities. |

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.
