Axial-flux PM disk generator with magnetic gear for oceanic wave energy harvesting
Dobzhanskyi, O.; Gouws, R.; Hossain, E.; Amiri, E.; Grebenikov, V. (IEEE, 2019)Magnetic gears (MGs) offer many advantages over mechanical ones due to their contactless mechanism of torque transfer. With the flourish of this new avenue of research, a new breed of MGs has been designed that are well ... -
Design of an intelligent controller for a renewable energy efficient bulk storage tank
Pelser, W.A.; Gouws, R. (2015)The national electricity supplier in South Africa is experiencing difficulty in providing the required electricity, due to compliance with environmental regulations and the continuous price increase of commercial fuels. ... -
Development of a quadcopter for power line inspection
Wilken, N.J.; Gouws, R. (2014)The inspection of transmission lines is to be done annually. It is proposed that a quadcopter is used to do the inspection of these transmission lines. The modelling of the quadcopter was done by studying its physical ... -
Improving the efficiency of single phase asynchronous machines
Gouws, Rupert; Van Jaarsveldt, Heino (EE Publishers, 2014)Globally around 40% of the electricity supplied to the industrial and mining sectors is consumed by electric motorised systems and for South Africa around 60% of the electricity supplied to these sectors is consumed by ... -
Investigation and efficiency analysis: 405 km transmission line with series compensation
Gouws, R. (Crown Publications, 2012)This article presents an investigative case study and efficiency analysis of the 405 km, 420 kV transmission line between Insukamini substation in Bulawayo, Zimbabwe and the Matimba thermal power station in South Africa ... -
Measurement and verification baseline development and service level adjustments for fridge plant systems
Gouws, R.; Grobler, L.J. (2009)In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ... -
Nie-indringende monitering van elektriese kabels in die industriële sektor om faling en kragonderbrekings te beperk
Van Jaarsveldt, H.; Gouws, R. (2014)Condition monitoring of electrical cables can prevent cables from failing prematurely. Partial discharge (PD) is the main source for degradation of the insulation material of medium-voltage cables. The well-known capacitor ... -
Novel measurement and verification of irrigation pumping energy conservation measures under incentive-based programmes
Storm, M.E.; Gouws, R.; Grobler, L.J. (ERC, UCT, 2018)In most countries the agricultural sector, especially crop irrigation, is a considerable energy consumer. Farm irrigation studies in South Africa showed that energy and water is wasted on a large scale and there is a large ... -
Optimal switching-flux motor design and its cogging effect reduction
Dobzhanskyi, O.; Gouws, R.; Amiri, E. (IEEE, 2017)This paper presents an optimal switching-flux motor design in terms of cheap cost, simple manufacturing process, and easy maintenance. The high cogging effect and its impact on the performance of the machine is studied by ... -
Source stabilisation of single-phase induction motor-pump configurations
Gouws, R.; Swanepoel, M. (EE Publishers, 2012)The effect of source stabilisation on the energy consumption and harmonic distortion of a single-phase induction motor-pump configuration for a swimming pool in South Africa
