| Abstract | Ageing and degradation mechanism of linear low density polyethylene (LLDPE)-natural rubber (NR) composites after subjected to partial discharge (PD) activities is presented in this paper. The LLDPE-NR blends and LLDPE-NR composites containing nano-sized fillers, montmorillonite (MMT) and Titanium (IV) Oxide (TiO) were produced by a twin-screw extruder. The Maleic anhydride grafted linear low-density polyethylene (LLDPE-g-MAH) of 10 wt% was added as a compatibilizer. The entire of LLDPE-NR blends and composites were conducted with partial discharge test according to CIGRE Method II. Surface of LLDPE-NR blends and composites specimen showed severe chalking and discoloration on the side of high voltage electrode. The surface morphological changes were studied in detail using Scanning Electron Microscope (SEM) and Energy Disperse X-ray spectroscopy (EDX). The SEM micrographs of aged LLDPE-NR specimens showed that the surface structure become porous and degradation appeared. The longer of ageing time result the more severe degradation on the surface of specimens. In addition, the morphological analysis result based on the EDX spectrum of the degraded LLDPE-NR composite specimen revealed the existence of O peak anticipates that the oxidation of the insulation specimen proceeded. |

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.
