| Abstract | An environmental stress chamber was built to investigate the long-term degradation mechanisms of the materials. Within the chamber a number of stresses were applied simultaneously to model glass reinforced plastic insulating rods. The rods were subjected to cantilever mechanical loads and electrical stresses. They were also sprayed with, or immersed in, water as the tests progressed. The temperature of the air surrounding the insulators was also controlled. In this way the stresses which are applied to insulating rods in service were simulated. The environmental stress chamber was linked to a personal computer which monitored and recorded the progression of creep and leakage current. The behavior of silicone modified polyester rods has been examined. The results available to date are presented. The change in the rates of creep with different mechanical loads is discussed. In addition, the uptake of water over prolonged periods has been studied. |

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.
