| Abstract | Modified high-density polyethylene (m-HDPE) is a candidate for high-voltage solid DC cable insulation. Based on the space-charge measurements on thick modified HDPE samples (1.5 mm), it was reported that modified HDPE contained relatively small amount of space charge and showed high breakdown strength. We measured space-charge distribution in thin m-HDPE samples (50 /spl mu/m) by using the laser-induced-pressure-pulse method in order to clarify effects of charge injection on the space-charge characteristics and electrical conduction. The samples with Au electrodes showed positive home space charge at room temperature but negative charge became dominant at higher temperature. These charges are due to injection from the electrode. The space-charge behaviour at voltage polarity reversal suggested that these space charges affected the breakdown characteristics. The samples with a semiconducting layer showed space-charge and conduction characteristics different from those with metal electrodes. The change was partly attributed to the diffusion of impurities during the hot-press process for applying the semiconducting layer. |

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.
