Design and heat flow analysis of a commercial energy efficient in-line water heating system
(Emerald, 2014)
In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ...
Active magnetic bearing condition monitoring
(Emerald, 2013)
In this paper, condition monitoring of the internal parts of a radial active magnetic bearing (AMB) system is performed by means of Cepstrum analysis, Wigner-Ville Distributions (WVD) and enveloped Equi-Sampled Discrete ...
Real-time displacement analysis and correction system for vibration forces on rotor of rotational active magnetic bearing system
(Emerald, 2011)
The real-time displacement analysis and correction of vibration forces on the rotor of a rotational active magnetic bearing (AMB) system were performed. The real-time system performs four main tasks: fault detection, fault ...
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. ...
Measurement and verification baseline development and service level adjustments for fridge plant systems
(2009)
In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ...
Development of a controller for fuel cell and supercapacitor application
(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 ...
Nie-indringende monitering van elektriese kabels in die industriële sektor om faling en kragonderbrekings te beperk
(2014)
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 ...
Study on energy losses in industrial sector caused by low actual efficiency of induction motors
(IEEE, 2014)
This paper presents a study on energy losses in the industrial sector caused by low actual efficiency of induction motors (IMs). The main reasons are discussed and an efficiency analysis of a 3-phase induction motor, ...
Improving energy consumption of an induction motor by design of a power factor correction system and estimation of it's saving on a large scale
(IEEE, 2014)
Power factor correction (PFC) is common in commercial and industrial applications. A need to extend its application increased with the dwindling natural resources used for power generation and also exceeding energy demand, ...
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 ...
