| Abstract | Partial discharge testing is widely used to monitor the condition of the electrical insulation in high voltage motor and generator stator windings. In the past, virtually all online partial discharge testing has been performed on a periodic basis, for example every six months. Two different monitoring systems have been developed which enable the continuous measurement and storage of partial discharge data. The first system is a full-featured system which captures all the partial discharge information, including a pulse magnitude and pulse phase analysis. This system duplicates all the features of a portable instrument, and is intended for use on high voltage machines which see many load changes, are equipped with online expert systems, or are in remote locations. The second system which has been developed is intended for medium voltage motors (2.3 to 4.1 kV). For some failure processes on such motors, partial discharges may only yield a few weeks or months of warning of failure. Thus, continuous partial discharge measurement is essential to give the maximum possible warning time. This system has only basic capabilities for data collection, in order to minimize cost. Both systems employ advanced electrical interference separation methods to minimize the risk of false indications and the need for expert intervention. |

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.
