| Abstract | Detecting, locating and evaluating of partial discharges (PD) in the insulating material, terminations and joints provides the opportunity for a quality control after installation and preventive detection of arising service interruption. A sophisticated evaluation is necessary between PD in several insulating materials and also in different types of terminations and joints. For a most precise evaluation of the degree and risk caused by PD it is suggested to use a test voltage shape that is preferably like the same under service conditions. Only under these requirements the typical PD parameters like inception and extinction voltage, PD level and PD pattern correspond to significant operational values. On the other hand the stress on the insulation should be limited during the diagnosis to not create irreversible damages and thereby worsening the condition of the test object. The paper introduces an oscillating wave test system (OWTS), which meets these mentioned demands well. The design of the system, its functionality and especially the operating software are made for convenient field application. Field data and experience reports will be presented and discussed. This field data serve also as good guide for the level of danger to the different insulating systems due to partial discharges |

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.
