| Abstract | Surface flashover is one of the major issues in electrical insulation in power systems operating either in space (vacuum or partial vacuum) or atmospheric (earth-bound) environments. Development of new and advanced materials to be used in power systems requires extensive studies on electrical insulation characteristics of these materials before they can be used in commercial systems. In this paper, we present experimental results of surface flashover characteristics in partial vacuum of epoxy resin and epoxy resin cast with powdered Al/sub 2/O/sub 3/. The flashover studies were conducted using DC and AC signals separately. Surface flashover voltage and current wave forms of the samples and light emission wave form and video images during the breakdown were recorded. Optical data collected by a video camera along with the PMT light emission data are analyzed and the analysis results of the optical emission characteristics of surface flashover are presented. The samples used in the experiments were produced by using either epoxy resin of known properties or by mixing known quantities of Al/sub 2/O/sub 3/ with epoxy. The electrode material placed over the dielectric samples was copper. |

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.
