A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)
In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ...
Towards PQ regulation in Southern Africa
(IEEE, 2009)
This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective
On the development of a power quality benchmarking model
(IEEE, 2009)
The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ...
Data mining: a technique used to extract information from tan delta measurements on medium voltage induction motors
(IEEE, 2007)
The study attempted to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes were used to gain insight into the data and the condition of the insulation ...
A qualitative assessment of the insulation systems of medium voltage induction motors
(IEEE, 2007)
The research was an attempt to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes was used to create a model to gain insight into the data and the ...
Status of international interconnections and electricity deregulation in Africa: an overview of the current status in Southern Africa
(IEEE, 2004)
The Southern African power system is in a state of
flux. The grid is expanding and more interconnections are being
made. However, vastness of the area and the low power
consumption density in most African countries makes ...
Linear model of a closed three-shaft Brayton cycle
(IEEE, 2004)
A linear model of a closed three-shaft Brayton cycle is developed. The model is intended to give an understanding of the dominant dynamic behavior in a nuclear power system that utilizes a closed three-shaft Brayton cycle. ...
The development of a flexible rotor active magnetic bearing system
(SAIEEE, 2007)
A design process comprising aspects of modelling and analysis is developed, implemented and verified for a flexible rotor active magnetic bearing system. The system is specified to experience the first three critical ...
Linear model of a closed three-shaft Brayton cycle
(SAIEEE, 2006)
A linear model of a closed three-shaft Brayton cycle at normal power operation is
developed. The model is intended to give an understanding of the dominant dynamic behaviour in a
nuclear power system ...
The effect of thermal drying on the mechanical strength of South African coal
(SAIMM (The South African Institute of Mining and Metallurgy), 2008)
