| Abstract | During the last few decades, partial discharge measurement and analysis have been considered one of the most important test methods for evaluating the quality of electrical machines and insulating systems. Test methods based on potential free capacitive and/or inductive couplers have taken place as well as methods based on the galvanic circuit with measuring impedance. These potential free couplers detect the electromagnetic field that is generated by partial discharge activity. The partial discharge detection, with using of the capacitive coupler, was the main reason to perform the measurements. The conclusions of the test are presented in this paper. Furthermore, the analysis of partial discharge of several physical models was performed because of the coupler's calibration and sensitivity evaluation. The different methods and apparatuses were used for partial discharge detection with the aim of the accuracy and sensitivity of the potential free method determination. The diagnostic equipment consists of a wideband analog apparatus, a digital apparatus, couplers and measuring impedance. The measurement was done according to IEC 270 standard. The capacitive couplers have been used as well for performing the potential free test method measurement. |

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.
