| Abstract | It has been observed that voltage waveforms generated by power electronic converters may affect significantly the reliability of electric motor insulation. The electrical characterization of magnet wire for electric motor has been carried out through aging tests under different aging time. We have measured the space charge parameter (e.g., the number of charge, trapping energy) in magnet wire under pulse width modulated (PWM) voltages by thermally stimulated current (TSC) method in order to show correlation between trapping parameter and time to aging. Also, partial discharge quantities (e.g., inception voltage, repetition frequency, phase distribution of discharge) have been measured in this paper. In particular, a relationship between time to ageing and the parameters of the TSC curve was observed in the sample. Relation between PD quantities with space charge accumulation has also been observed. These phenomena, if confirmed, could be used to screen new materials for PWM voltage applications |

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.
