| Abstract | The energy absorbed from ultraviolet (UV) radiation affects some of the electrical characteristics such as leakage current (LC) on the surface of polluted silicone rubber (SiR) insulators, which may cause dry-band, arc discharge and loss of the unique characteristic of hydrophobicity, leading to material degradation in the form of tracking and erosion and/or flashover. This paper reports the results of the effect of UV radiation on textured and non-textured silicone rubber samples. Laboratory tests were carried out in two stages: a) applying the UV radiation in accordance with ISO 4892-2, with variable exposure/condensation cycle; b) inclined plane test (IPT) to evaluate tracking and erosion performance of both kinds of insulation samples as in accordance with IEC 60587. Ultraviolet treated samples showed a small increase of LC on their surfaces. The LC and applied test voltage are acquired continuously for later use as an indicator of the sample's condition. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
