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 super-capacitor photovoltaic streetlight with xLogic SuperRelay functionality
(IRET (Institute of Research in Engineering and Technology), 2013)
In this paper, the authors present and discuss the
design of a prototype super-capacitor photovoltaic (PV)
streetlight with xLogic SuperRelay (PLC) functionality.
Deep-cycle batteries used in solar electrical systems, ...
Energy management by means of fault conditions on active magnetic bearing systems
(IRET (Institute of Research in Engineering and Technology), 2013)
This paper presents the use of fault conditions on
active magnetic bearing (AMB) systems as an energy
management tool to improve the operation of AMB systems.
Fault conditions on AMB system are broadly classified ...
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 ...
Measurement and verification of load shifting interventions for a fridge plant system in South Africa
(ERC (Energy Research Centre), 2013)
In this paper, the author presents the measurement and verification methodology used to quantify the impacts of load shifting measures that are implemented on large industrial fridge plant systems in South Africa. A summary ...
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 ...
Performance analysis of a permanent magnet transverse flux generator with double coil
(IEEE, 2016)
One of the disadvantages of permanent magnet (PM) transverse flux machines is high magnetic flux leakage in the stator and rotor
cores. To improve the magnetic circuit of this class of machines, a generator with double ...
