Partial discharge simulations used for the design of a non-intrusive cable condition monitoring technique
(David Publishing, 2013)
The purpose of this paper is to investigate the effect of PD (partial discharge) activity within medium voltage XLPE
(cross-linked polyethylene) cables. The effect of partial discharge was studied by means of a number of ...
A permanent magnet motor with two degrees of mechanical freedom
(EE Publishers, 2013)
The effectiveness and advantages of an energy-efficient
concrete mixer drive using a synchronous permanent
magnet motor to develop helical rotor movement
Fly ash resistivity profiling for South African coal fired power stations
(David Publishing, 2013)
Particulate emission is a major problem in industrial processes, mainly power plants that make use of coal as a primary
source of energy. Stringent emissions limits, set by government organisations requires industries to ...
Environmental impact of an industrial compressed air system with a solar powered compressor in South Africa
(Sage, 2012)
Almost 14% of the electricity generated by the national energy supplier (Eskom)
in South Africa is sold directly to the mining sector and almost 20% is utilized
directly by the compressed air systems of the mining sector. ...
Design and cost analysis of an automation system for swimming pools
(EE Publishers, 2012)
A low-cost automation system to minimise energy consumption
of circulation pumps and to regulate the chemical
composition of the water in swimming pools
Analysis of a 405 km transmission line with series compensation
(EE Publishers, 2012)
This paper presents an investigative case study and energy efficiency analysis of the 405 km, 420 kV transmission line between Insukamini
substation in Bulawayo in Zimbabwe and the Matimba thermal power station in South ...
Induction motor efficiency analysis: direct torque, flux control
(EE Publishers, 2012)
In this study, two scenarios were
evaluated: where the induction motor
was controlled at a constant speed with
a variable thickness slab, and where
the speed of the induction motor was
controlled according to the ...
Design procedure of a line-start permanent magnet synchronous machine
(SAUPEC, 2014)
This paper presents a method for designing an LS-PMSM by dividing the design into sub-machine
components. Each of the individual sub-machine components is then designed using several classical machine
design principles. ...
Combining different computational techniques in the development of financial prediction models
(SCITEPRESS, 2014)
The prediction of financial time series to enable improved portfolio management is a complex topic that has been widely researched. Modelling challenges include the high level of noise present in the signals, the need to ...
A control algorithm approach for optimizing energy resources through power generation for a South African steel works plant
(SAIIE, 2014)
Numerous engineering plants have varieties of processes, where individual process flows are dependent on previous processes and operated by default or manual settings. Initial raw material feeds may fluctuate over time, ...
