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.

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 ...
Ontwerp van 'n energiebestuurstelsel vir optimale energieverbruik en effektiwiteit van 'n distribusievlakmikrokragnetwerk
(2014)
South African state-owned utility company, Eskom, is under severe pressure to ensure the stability and reliability of the national electricity grid. With a shortfall in capacity of the national electricity grid, the ...
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 ...
Measurement and verification of the Eskom irrigation pumping standard product programme
(2013)
Eskom Integrated Demand Management (IDM) initiated a funding mechanism termed the Standard Product Programme (SPP) to cater for smaller Energy Efficient (EE) projects. The impacts of these projects
also need to be assessed ...
