| Abstract | In order to investigate the influence of crosslinking on high field dielectric properties of crosslinked polyethylene, the observations of high-field AC dissipation current waveforms of electron beam (EB) irradiated crosslinked polyethylene (IR-XLPE) films at 90/spl deg/C were carried out by using the different gel fraction samples. These different gel fraction samples were obtained from a different layer of laminated films of 40 layers from the electron beam irradiation side. From the measurements of capacitance for each IR-XLPE sample, we found that the variations of capacitance with temperature depends on the gel fraction. If the gel fraction is high, then capacitance varies little with temperature and vice versa. From the results of high-field AC dissipation current waveforms under AC ramp voltage application, we have estimated the electric field dependence of tan /spl delta/ for each gel fraction sample. The results show that the dielectric properties at 90/spl deg/C depend on the position of film from the electron beam irradiation side. It seems to indicate the mobile carrier in high temperature region are strongly affected not only by the electric field and/or temperature but also by the gel fraction of polyethylene films. |

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.
