These consequences lead to interruptions and loss of power supply. Atmospheric conditions in general and the temperature in particular is still not fully understood under DC excitation, especially when the applied voltage approached the critical breakdown value. Temperature has a great influence on corona discharge. In this study, the impact of temperature on the spatial distribution of the electric field, which can also be considered as one space charge source under DC supply was studied. A laboratory size corona cage with an aluminum tern conductor at its center, for the experiments in the high voltage laboratory. The purpose of this study was to investigate the effect of the temperature on the spatial distribution on the DC conductor with the maximum DC voltage applied of ±175 kV and have a better understanding of the major factors that influence the spatial distribution processes under a high temperature. The corona camera version 8 (CoroCam8) was used to visualize the spatial distribution around the conductor. This has enabled to observe the effect of the temperature with the variation of the DC voltage, passing through inception voltage with the increased up to ±175 kV. The spatial distribution is denser when the temperature is high for the positive voltage and for the negative voltage.","PeriodicalId":344332,"journal":{"name":"2019 Southern African Universities Power Engineering Conference/Robotics and Mechatronics/Pattern Recognition Association of South Africa (SAUPEC/RobMech/PRASA)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116836038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, combination of high and low inertia loads such as fans, pumps and mills leads to an increase in residual bus voltage frequency decay rate; which often result in fast bus transfer scheme failing to execute. In-phase bus transfer scheme, although slower than fast bus transfer scheme; can be considered as an alternate transfer process to transfer load when main power supply is lost as a result of upstream equipment failure. Unlike in the case of fast bus transfer scheme, high decay rate of residual voltage frequency is favorable for in-phase bus transfer process; while circuit breaker closing time does not necessarily impact the performance of the transfer scheme. The paper investigates the application of in-phase bus transfer scheme to transfer load to an alternate supply when the main supply is lost in a power plant unit auxiliary power distribution system. Simulation results presented in the paper indicate that in-phase bus transfer scheme can be used to transfer draught fan motors to an alternate supply while maintaining stable boiler furnace pressure, and therefore maintain process continuity.","PeriodicalId":344332,"journal":{"name":"2019 Southern African Universities Power Engineering Conference/Robotics and Mechatronics/Pattern Recognition Association of South Africa (SAUPEC/RobMech/PRASA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116888750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a network of engineering faculties and schools in some Eastern and Southern African universities linked to a UK university with the aim of enhancing quality of engineering education and training. The project objective is to enhance the quality of engineering education and training through: academic staff secondment to industry; invitation of industry experts to university as guest lecturers; collaborative research with industry, industry supported curriculum review and knowledge sharing workshops. This paper presents the activities at Durban University of Technology and our efforts to enhance engineering training of technical staff through short-term industry internships and postgraduate studies. The goal is to produce graduate engineers and technicians: who possesses relevant skills, meet the expectations of modern industry and engineering professional bodies; graduates who are employable nationally and regionally. It is also expected to produce academic staff with enhanced practical experience and better teaching skills, which will enrich the relevant engineering curriculum at universities.","PeriodicalId":344332,"journal":{"name":"2019 Southern African Universities Power Engineering Conference/Robotics and Mechatronics/Pattern Recognition Association of South Africa (SAUPEC/RobMech/PRASA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130358711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
