dissertatic,11 submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the degree of Master of Science in Engineering, I.: Johannesburg, 1998 / Corona stabilisation is not a well understood phenomenon, consequently a rigorous theoretical description of how the merhanism operates does not exist. Furthermore, postulates on the prcJ'.tse physical processes that occur during corona stabilised breakdown are varied and conflicting. 1t was thus essential to develop a qualitative theory of how the mechanism operates around which a quantitative model could be constructed. To this aim, a detailed analysis of available modelling methods and empirical data from published works was carried out. This analysis together with additional finite elements modelling done as part of this work, leads to a proposed qualitative model which serves as a basis for a quantitative model developed to simulate corona stabilized breakdown from a fixed panicle defect. There is a favorable comparison between the predictions of the model and published measurements, thus imbuing optimism in the proposed method. The problem of measuring t: .;true charge deployed in a discharge is discussed and an experiment is designed to circumvent this problem.

The South African .economy was hit hard by the electricity crisis of 2008 where increasing demand for electricity outstripped the available supply that led to load shedding. Many jobs were lost, industries could not keep up with international competition and as a result jobs were lost in the process affecting many households in the country. This is the context within the debate around the introduction of private sector participation in the electricity industry to assist Eskom to meet the demand and stimulate economic growth. This dissertation examines the introduction of the Independent Power Producers and its impact on the industry. It has been found that to level the playing field in the industry, the horizontal structure of the electricity industry will have to disaggregate. International experience has shown that this structure is perfect for meeting the increasing electricity demand and for economic growth. / Thesis (MBA) North-West University, Mafikeng Campus, 2012
