| Abstract | Inverter-fed traction motors used in express locomotive experience the continuous square wave pulses voltage with significant harmonics and transients. The insulation aging mechanism under continuous square wave pulses is very different with the aging mechanism under sine waves. In order to study the influence of continuous square wave pulses voltage output by inverter, it is necessary to establish an appropriate method for investigating the ageing properties and failure mechanism of magnet wire insulation for the inverter-fed traction motor. However, the voltage values of existing pulse power sources are below 5kV, it can't meet the demands. In this paper, a new type of high frequency and high-voltage pulse power source is designed to investigate the influences of continuous square wave pulse voltage on insulation of traction motors used in express locomotive. It makes up of a square wave pulse generator and a high frequency transformer. Test results show that the square wave pulse power source can meet the test requirements of traction motor insulation evidently. |

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.
