| Abstract | Effective Contaminant Deposit Density (ECDD)-a new concept of the pollution level of silicone rubber composite insulators is introduced in this paper to study the transferency of hydrophobicity and the artificial contamination test method of composite insulators. A solid contamination layer method is adopted. The effective contaminant is defined as the dissolved salt from the contamination layer when the polluted sample or insulator is wetted. It is found that the ECDD is much less than the original artificially polluted salt deposit density (SDD). This phenomenon means that only part of the salts could be dissolved out when the polluted silicone rubber sample is wetted. Hence the lower ECDD is also the important reason why the silicone rubber insulator could always keep its excellent pollution performance besides the well-known reason that hydrophobicity caused an uncontinued water film on the insulator surface. Then ECDD or the ratio of ECDD/SDD, called solved ratio, could be used to describe the transferency of hydrophobicite. The lower solved ratio represents the more sufficient transference. |

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.
