| Abstract | In order to determine feasibility of SF/sub 6/ gas insulated equipment for HVDC substation technology, a testpole was built and subjected to a long term test of 2 years. The test pole consisted of slightly modified commercially available 550 kV AC and 800 kV AC gas insulated components. The components were SF/sub 6/-air bushings, an air insulated arrester, a SF/sub 6/ insulated arrester, a SF/sub 6/ oil bushing, disconnecters, bus ducts and conical spacers. Testing involved continuous DC stress (500 kV and 600 kV) lightning and switching impulse tests, polarity reversal tests and ultrasonic partial discharge measurements. Thermal cycling was performed during de load and went uninterrupted for more than 1 year. No internal breakdowns occurred during any tests. Visual inspection of the spacers at various times during tests and final disassembly revealed no visible flashover traces. The testing has demonstrated that the gas insulated technology is well suited for commercial HVDC applications. |

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.
