Data acquisition system for capturing dynamic transients in a control valve
(IEEE, 2004)This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ... -
Data logger and companion application for time-of-use electricity
(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 ... -
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 ... -
DC power quality emulator
(IEEE, 2020)Currently, no dc power quality standards exist. The lack of dc power quality (PQ) standards can be addressed by, amongst others, evaluating the impact of PQ deviations on consumer end equipment. A voltage disturbance ... -
Dc-bus voltage balancing controllers for split dc-link four-wire inverters and their impact on the quality of the injected currents
(IET, 2017)The increasing share of single-phase distributed generation units in low-voltage grids causes voltage unbalance problems and overvoltages. Therefore, the need for power quality improving control strategies of grid-connected ... -
Decongestion of the distribution grid via optimised location of PV-battery systems
(IET, 2017)In order to achieve the energy targets for 2020, further integration of renewable energy sources is required. Hence, there was a need to investigate possible solutions to achieve a reliable network without loss of production. ... -
Delevitation modelling of an active magnetic bearing supported rotor
(s.nCurran Associates, 2010)For active magnetic bearings (AMBs) to be used with confidence in industrial applications, the safe failure of the AMB system should be guaranteed. The exact behaviour of the rotor on the backup bearings (BBs) is relatively ... -
Demonstrating an interpretive data collection and analysis process for a DSR project
(Czech institute of academic education z.s, 2014)Design science research has two essential processes, design and evaluation, supported by various approaches. Two of these activities, namely problem identification and evaluation, require qualitative data to be gathered ... -
The dependence of optical polarisation of blazars on the synchrotron peak frequency
(PoS, 2017)The RoboPol instrument and the relevant program was developed in order to conduct a systematic study of the optical polarisation variability of blazars. Driven by the discovery that long smooth rotations of the optical ... -
Describing a design thinking methodology to develop sustainable physical activity and nutrition interventions in low resourced settings
(Springer, 2018)The objective of the study is to describe how design thinking as a participatory process can be applied in determining how sustainable physical activity and nutrition interventions should be implemented in a low resourced ... -
Design considerations of the PM transverse flux linear motor for an urban-type electromagnetic train
(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
(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
(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
(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
(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 e-Registration Prototype Using HCI Principles: With Specific Reference to Tax Registration
(IBIMA, 2014)This paper introduces an initial web form prototype for first-time taxpayer registration in South Africa. At present no online tax registration system is currently available. The researcher would like to stress the fact ... -
Design of an intelligent controller for a renewable energy efficient bulk storage tank
(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. ... -
Design optimization of a line-start PMSM considering transient and steady-state performance objectives
(IEEE, 2017)This paper investigates the use of the Taguchi method based regression rate optimization method for the design of line-start permanent magnet motors. A weighted factor multi-objective (MO) technique is used to take into ...
