Energy audit of the Howard College Campus of the University of KwaZulu-Natal.
Load growth projections on South Africa's electricity demand indicate that Eskom's spare capacity will be eroded by the year 2005. In the late 1960s South Africa experienced electricity shortages and Eskom embarked on a ...
Assessment of the electrical performance of the Cahora Bassa HVDC scheme.
The aim of this study was to assess the electrical performance of the Cahora Bassa HVDC scheme. For practical reasons a database was developed to hold and analyse the performance data. Microsoft® Access 2002 relational database ...
Safety of low voltage switchgear STAs in South Africa – Part 2.
(EE Publishers., 2005)
This article is Part 2 of a two part article. Part 1 was published in the October 2005 issue of ENERGIZE. A technical analysis was undertaken to investigate the safety implications of the introduction of the category ...
Suppression of transients across the tap windings of an auto-transformer.
(EE Publishers., 2005-06)
For the energy transfer between the various voltage levels of the Eskom national grid, auto-transformers are mainly installed. These auto-transformers are interfaced with the distribution network.
A theoretical and experimental investigation into fire induced flashover of high voltage transmission lines.
This thesis documents a research study of High Voltage transmission line faults induced by fire. Conductor to conductor and conductor to ground flashovers have been experienced by electricity utilities around the world ...
Safety of low voltage switchgear assemblies in South Africa – Part 1.
(EE Publishers., 2005)
A technical analysis was undertaken to investigate the safety implications of the introduction of the category Specially Tested Assembly (STA) into the South African standard SANS 1473-1:2003. The testing requirements ...
Eskom’s proposed strategic research into HVDC transmission.
(EE Publishers., 2005-07)
Eskom has recently started a large research and development programme for the study of long-distance HVDC transmission in Sub-Saharan African conditions. This paper explains why the research is being done, what its strategic ...
Enhancing transient stability of power systems using a thyristor controlled series capacitor.
The continuously growing demand for electric power requires transmitting larger amounts of power over long distances. An economically attractive solution to increase the power transfer through a long interconnection (up ...
Effect of ADLash opitical fibre cable on corona onset gradient and electric fields around the shield wire of the Apollo-Cahora Bassa HVDC line.
ADLash® is the trade name for an optical fibre cable attached to a transmission line shield wire using aramid-reinforced bands. The installation of this type of optic fibre cable has been considered for the HVDC line from ...
Modelling, simulation and robust control of a Benson boiler during hot startup.
Large boilers have typically been designed for continuous operation from 60-100% load. With restructuring of electrical supply and in some cases because of local fuel supply constraints, some of these boilers are run for ...
