Intelligente beheer van ’n hernubare, energiedoeltreffende tenk vir melkboerderye
(AOSIS, 2015)
To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient
bulk storage tank using solar power was designed. The system uses thermoelectric cooling
modules as a supporting cooling ...
Prototype line crawler for power line inspection
(David Publishing, 2013)
In South Africa, electricity is supplied through thousands-of-kilometers of overhead power cables, which is owned by
Eskom the national energy supplier. Currently monitoring of these overhead power cables are done by means ...
A review on thermoelectric cooling modules: installation design, performance and efficiency
(Academic Journals, 2013)
A thermoelectric cooling module (TECM) is defined as a solid-state heat pump and present advantages
(for example, no moving parts and no harmful gasses) over other refrigeration technologies. However,
to optimally use ...
Analysing two control methods of shunt active filters for unbalanced load
(Nagpur: Yeshwantrao Chavan College of Engineering, 2014)
A three-phase shunt active filter is used for current and/or voltage unbalance compensation. Two control schemes with two
different theory, instantaneous power theory and Generalized Fryze are considered to compensate the ...
Efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill
(Energy Research Centre, University of Cape Town, 2015)
This paper presents an efficiency analysis of an
induction motor with direct torque and flux control
at a hot rolling mill in South Africa. Two scenarios
were evaluated: 1) where the induction motor was
controlled at ...
Nie-indringende monitering van elektriese kabels in die industriële sektor om onklaarraking en kragonderbrekings te beperk
(AOSIS, 2015)
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 ...
Factors influencing the performance and efficiency of solar water pumping systems: a review
(Academic journals, 2012)
The world is having an energy crisis and currently there is a strong drive towards renewable energy. A renewable energy option is solar energy, where by means of photovoltaic (PV) modules electrical energy can be produced. ...
Efficiency and cost analysis of a designed in-line water heating system compared to a conventional water heating system in South Africa
(ERC (Energy Research Centre), 2012)
In this paper, the authors compares the efficiency and cost of a designed in-line water heating system with a conventional water heating system (geyser) in South Africa. The paper provides an overview on water heating ...
Impact of frequency switching on the efficiency of a fully suspended active magnetic bearing system
(Academic journals, 2012)
Due to the rising energy (and electricity) cost it is essential that an active magnetic bearing (AMB) system is operated as efficiently as possible. Frequency switching caused by an external source can cause an AMB system ...
Using dynamic model of PEM-Fuel Cell supplying the load by the Z-source inverter with a novel control strategy
(Staff Research Council of Yeshwantrao Chavan College of Engineering (YCCE) , Nagpur, India, 2014)
A new dynamic model is developed in this paper to connect PEM Fuel Cell (PEMFC) to a Z-source inverter (ZSI). This
model is used to analyse the behaviour of a fuel cell by providing a polarization curve. A controller is ...
