Data logger and companion application for time-of-use electricity
Vermaak, Nicojan; Gurusinghe, Nicoloy; Gouws, Rupert; Ariyarathna, Thilanga (IEEE, 2018)Electricity generation is becoming more expensive, hence Time-of-Use (ToU) electricity tariff structures, such as Eskom Megaflex are implemented. The companion application is an integrated solution designed for use with ... -
Design considerations of the PM transverse flux linear motor for an urban-type electromagnetic train
Dobzhanskyi, Oleksandr; Gouws, Rupert; Amiri, Ebrahim (IEEE, 2018)This paper presents six different designs of the permanent magnet transverse-flux linear motor applied to an electromagnetic train. The initial design of the motor was modified to improve its magnetic characteristics. ... -
Design of a non-intrusive cable condition monitoring technique by means of partial discharge
Van Jaarsveldt, H.; Gouws, R. (2013)The purpose of this paper is to discuss the design of a non-intrusive condition monitoring technique for medium- and high-voltage power cables. Partial discharge (PD) was used to design the non-intrusive condition ... -
Design of a prototype power line inspection robot
Du Plessis, N.W.; Gouws, R. (2013)The purpose of this paper is to provide the design of a prototype power line inspection robot for the monitoring of Eskom transmission lines. It should also determine if an inspection robot would be a feasible solution ... -
Design of a prototype ultra-capacitor solar panel street light
Van Niekerk, A.E.; Gouws, R. (2013)The purpose of the paper is to describe and discuss the design of a prototype ultracapacitor solar panel street light. The effect of ultra-capacitors as an energy storage device in a solar panel street light is evaluated. ... -
Design of a transmission line monitoring solution for an unmanned quadcopter
Van Rooyen, T.; Gouws, R. (2014)Eskom owns thousands of kilometres of transmission lines that need to be inspected in order to plan maintenance. Current methods of inspection are costly and ineffective and could pose safety risks. Systems already developed ... -
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 controller for fuel cell and supercapacitor application
Rautenbach, H.J.; Gouws, R.; Bessarabov, D.; Kruger, A.; Human, G. (CATSA (Catalysis Society of South Africa), 2014)The growing demand for energy in the world causes a lot of pressure to the environment and the resources used to supply the energy. To ensure a continuous, more reliable and environmentally friendly energy supply system ... -
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 ... -
Efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill
