Modeling the pulse profiles of millisecond pulsars in the second LAT catalog of γ-ray pulsars
(AIP, 2012)
Significant γ-ray pulsations have been detected from ∼40 millisecond pulsars (MSPs) using 3 years of sky-survey data from the Fermi LAT and radio timing solutions from across the globe. We have fit the radio and γ-ray pulse ...
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 ...
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. ...
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 ...
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 ...
A review on switched reluctance machines for electric vehicle
(IEEE, 2016)
Nowadays, switched reluctance machines (SRM) are gaining interest in the scientific community due to the advantages they offer. The SRM offers an overall efficiency similar to an induction motor of the same rating, since ...
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 ...
