Recently, with the rapid development of computer based signal processing, it is possible to identify the source of partial discharge (PD) signals originating from complex insulation structures under varied operating conditions. The research on PD pattern classification is mostly performed in the time-domain but there is also an increasing trend to undertake frequency-domain analysis. In this research work, an experiment has been carried out on an 11KV, single-core 240 mm/sup 2/ XLPE cable. The operating conditions are varied using two parameters which are the soil condition in terms of soil thermal resistivity and cable loading in terms of core temperature. The time-domain electrical PD signals obtained from a PD measurement system are transformed into frequency spectrum by short-time fast Fourier transform (STFFT) using Matlab toolbox. In order to carry out the PD pattern classification, nine frequency-domain statistical descriptors are identified for the present work. A database for the range of values of the nine descriptors have been developed using PD signals obtained from one of the soil thermal resistivity at normal full load working temperature that is identified as standard. The values of the descriptors obtained from signals corresponding to other operating conditions stated earlier are then compared against the standard database and the number of successes is measured in terms of the commonly used recognition rate. The analysis of the results has clearly indicated that the proposed methodology has the ability to classify PD patterns originating from the cable under varied operating conditions.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.

Many companies have sought to offset total cost of manufacture by introducing foreign labor into the cost equation, Material+Labor+Overhead=Manufacturing Cost. Since US motor manufacturing is a mature industry, it has resulting high labor and overhead costs compared to less developed or under-developed countries. In addition, American motor manufacturers have to factor in high regulatory tax burdens and meet regulating bodies' requirements. Thus, the total cost of manufacture in US is substantially higher. In order to sustain electric motor manufacture in the US requires new methods of processing motors to make them more cost effective. One such method is automation of assembly combined with innovations such as self-bonding magnet wire.","PeriodicalId":274147,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Technology Conference (Cat.
