Electronic tensioners usual in trade are not able to compensate fluctuations of the tensile force satisfactorily, when bobbins with a non-circular cross-section are wound. In this case considerable fluctuations result from the accelerations taking place during the whole winding process. Two different approaches are presented in this paper to keep the tensile force within a restricted tolerance range in order to facilitate a perfect layer winding and to reduce the mechanical stress of the wire.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

Many large critical motors in fossil and nuclear generating stations have surge capacitors installed on their phase terminals. On-line PD measurements on eight such motors were done without contact with high voltage terminals in Ontario Power Generation (OPG, earlier Ontario Hydro) by installing high (or radio) frequency current transformers (HFCT or RFCT) and line frequency current transformers (LFCT) on the grounding leads of the surge capacitors. The PD and line frequency voltage signals were picked from the HFCT and the LFCT, respectively. Passive filters were used to eliminate interference from high magnitude pulses generated by exciters in the generating station. A commercial instrument analyzed the PD pulses in terms of magnitude and relationship to the phase of the line voltage. Measurements have been repeated several times. This paper presents the the results obtained so far. Separate off-line tests on a similar motor showed that the HFCT method is at least as sensitive as the conventional OPG method, which uses a capacitive coupler, a wide-band filter, and an oscilloscope.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

In addition, operation in the air environment doesn't offer the dielectric advantages of operating in high pressure hydrogen. These three insulation stress factors are well known and for the most part understood with respect to the factors taken into account when designing air cooled generator stator windings. These three stress factors are considered when selecting the coil materials, the coil geometry, and the rating capabilities of the stator coil. With the movement to increasing the power density of air-cooled generators, it has become more critical to be sure the design constraints are met in the stator coil design. In addition, the coil materials and processing must be improved to meet the demands of the increased stress factors. In addition to the use of high performance coil materials, great improvements have been made in the analysis, testing, and the use of more sosphicated instrumentation for verification testing. The stator coil insulation system used in the modern air cooled generators are designed to meet the high demands placed on the system during generator operation.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

The diagnostic tool uses a fuzzy interface to separate firstly PD pulses in classes according to their shape, then applies statistical analysis of PD pulse height and phase on the pulses recorded in each class. A fuzzy logic inference engine is then employed to provide indications on the nature of the defects generating PD. In the paper, a short description of the proposed diagnostic tool is presented along with its application to different insulating systems, i.e., cable joints, cables and high frequency transformers.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

In response to this demand the types of electrical insulating resins used have shifted from solvent containing resins to solventless type resins. The solventless types include unsaturated polyester resins and epoxy resins. While these products are solventless a certain amount of VOC can be detected. In unsaturated polyester resins this VOC is attributed to the monomer portion of the resin. Although manufacturers have significantly reduced their VOC emissions there is still a push for further reductions. This trend has prompted resin manufacturers to review their resin systems. One of the strategies for lowering VOC emissions in unsaturated polyester resins is the reduction or elimination of the monomer contained in these resins. This paper highlights the development work done to develop one such resin system.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.
