| Abstract | A generation of PD (partial discharge) in motor windings is a significant problem to develop a high voltage driving system, which is expected to improve the motor efficiency. A space charge accumulation in an insulating material of motor windings has been pointed out as one of reasons, for the PD generation because the space charge accumulation sometimes enhances the electric field in an insulating material. Therefore, measurement of the space charge in the insulating layer of motor windings is required. Space charge accumulation characteristics in film shape sample are usually measured using the PEA (pulsed electro-acoustic) method. However, since a manufacturing process of actual windings wire is different from that for film shape sample, the characteristics are assumed to be different from actual one. It means that it is difficult to evaluate the influences of the space charge on the insulating layer of the actual wire from the measurement result of the film shape sample. Therefore, in this research, we tried to measure the space charge distribution in the insulating material of actual enameled wires using an improved PEA measurement system. As a result, it is found that there are different types of space charge accumulation characteristics, even between nominally same insulating materials. |

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.
