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 ...
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 ...
Efficiency analysis of a three-phase power transformer
(Crown Publications, 2015)
Transformers are key elements in the industrial processes into
which they are integrated. Reliability is crucial to ensure uninterrupted power supply to motors, furnaces and smelters used
in a wide variety of applications ...
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 ...
Development of an axial suspended AMB experimental bench for load and disturbance tests
(UNAM (Universidad Nacional Autónoma de México), 2015)
This paper provides the development of an axial suspended active magnetic bearing (AMB) experimental bench for load and disturbance tests.
This test bench must be capable of levitating a 2 kg steel disc at a stable working ...
Generation of ozone and hydrogen in a PEM electrolyzer
(CRC Press, 2015)
Energy management system for a residential grid-tied micro-grid
(IEEE, 2015)
With the national power grid under
tremendous pressure, there are enormous pressure exerted
on residential electricity consumers to cut-back on
electricity consumption to ensure a reliable supply. This has
led to ...
Verifying the cooling capacity and power consumption of thermoelectric cooling holders for vaccine storage
(IEEE, 2015)
The purpose of this paper is to verify the power
consumption of different topologies of cooling system for the
storage of vaccine in a portable solar powered vaccine carrier
box for the domestic use in South Africa. The ...
PEM electrolysis for hydrogen production: principles and applications
(CRC Press, 2015)
An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been ...
Sulphur trioxide decomposition with supported platinum/palladium on rutile catalysts. 1. Reaction kinetics of catalyst pellets
(Elsevier, 2015)
An investigation was undertaken to evaluate the intrinsic reactivity, stability and associated diffusional parameters of catalyst pellets consisting of platinum and palladium on rutile for the conversion of sulphur trioxide ...
