Bruintjies, Mark Anthony Gaunt, C Trevor Electrical Engineering Includes bibliographical references. Keeping generators available on-line is a major factor in achieving maximum productivity in power generation. During operation, generator components are continuously exposed to thermal, electrical, mechanical and environmental stresses. The complex interactions of these stresses degrade the components resulting in a reduction of useful life. An integral part of satisfactory operation of high voltage (HV) electrical rotating plant relies upon the integrity of the electrical HV insulation of both the rotor and stator. The combined effect of the above mentioned stresses results in ageing of the insulation, which if not detected, results in premature failure in service. Deterioration of the stator bar insulation is a leading factor for determining the serviceability of hydro generators. Unexpected and expected stator bar failure can result in forced outages and costly emergency repairs. This research will deal with the deterioration of stator bar insulation in air-cooled hydro generators only. 2015-01-27T08:51:25Z 2015-01-27T08:51:25Z 2012 Master Thesis Masters MSc http://hdl.handle.net/11427/12294 eng application/pdf Department of Electrical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
