| Abstract | Pollution flashover on high voltage insulators is a major problem for power transmission lines. It is a very complex issue due to many factors i.e. modelling and design difficulties, unknown environmental stress, non-uniform distribution of pollution on insulator surface and different pollution levels in different regions. The deposition of pollution layers on high-voltage (HV) insulator surface is the first stage of pollution flashover. The aim of this paper is to investigate the influence of dry band formation and its characteristics on HV insulators with different salt mixtures and variable pollution layer thickness. The non-uniformity of the contaminant distribution, wetting and drying process leads to the development and formation of multiple dry bands on the insulator surface. From the test results it is clear that the dry band formation is not uniform with different salt mixtures. COMSOL Multiphysics™ has been used to simulate an insulator surface to find the variation of dry band formation with applied voltage. In particular, this paper aims to obtain a better reproduction method of pollution layers deposited on insulators which is very important to improve the reliability of HV insulators installed near coastal regions. |

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.
