NalediPandor_100x133Teaching innovation
An address by DST Minister Naledi Pandor

Can innovation be taught? Can we teach young people how to change the world? Eskom thinks so. Those of us in government certainly think so. And so do young people. If only adults and politicians held the same belief!... (more)
Eileen Leopold SAEECYes we can!
by Eileen Leopold, SAEEC
 
There are still many opportunities in the energy infrastructure markets. These include smaller to medium sized projects and those that involve "niche" technologies. This is exactly the space in which many South African electro-technical companies excel... (more)
Annette ThompsonThe struggle for power...
by Chris Yelland, EE Publishers

Value for money
by Andrew Overall, ECA
 
The common law of business prohibits paying a little and getting a lot - it can't be done. If you deal with the lowest tenderer it is well to add something for the risk you run, and if you do that, you will have enough to pay for something better... (more)
Electrical safety - working under or near power lines 
by Zizo Tshisela, Eskom

Exposure to unsafe working conditions near Eskom electricity installations is a major cause of injuries and deaths among construction workers. Losing people to electrical accidents means... (more)
Testing of single phase supply
by Chris Koen, ECA
 
The instrument to be used is the normal multi-meter, set on the resistance (ohm) scale or buzzer. Disconnect one end of the circuit breaker. Clip one lead of the tester on to the terminal of the circuit breaker... (more)
Telemanagement of public streetlighting infrastructures
by Jason Smith, Beka 
 
Public lighting designers and managers are required to provide far more reliable infrastructures, adopt ever increasing energy saving principles and to provide effective on-demand and proactive maintenance of these systems... (more)
Safe disposal of fluorescent tubes and CFLs  
by Brian Turner, Specialised Protein Products
 
Following all the discussions on the safe disposal of fluorescent tubes and CFLs, we fabricated a fluorescent tube breaker for the safe disposal of used tubes... (more)
Nickel-cadmium batteries in emergency lighting
by Kyle Mason-Jones and Harro von Blottnitz, UCT
 
The South African building regulations require, in certain situations, the installation of emergency lighting and illuminated emergency signage which is able to operate independently of the mains power supply... (more)
Energy savings obtained by varying voltage supply to induction motors
by C D Pitis and M W Zeller, BC Hydro Power Smart, Canada 
 
It is known that some squirrel cage motors run for relatively long periods close to no-load. This suggests that such motors are either grossly oversized or are cycling with significant time spent near no-load or idling duty... (more)
The anatomy of an airport
by Kobus Burger, SSI Engineers and Environmental Consultants
 
An airport is probably one of the most ICT intensive users, running on the TCP/IP platform, integrated via Virtual Private Networks (VPNs), and sharing a common communications system... (more)
Coping with the replacement of safety categories
by Derek Jones, Rockwell Automation
 
The evolution and application of safety standards requires the intensive use of complex, programmable technologies linked through communication networks to faster, accurate and powerful actuators... (more)
Bringing greater awareness to power consumption
Information from APC by Schneider Electric

The Schneider Electric group believes that every person and every business worldwide is going to be affected by the energy challenge... (more)
Effective earthing
Information from Major Tech 

Earthing is achieved by providing a path for fault current to flow safely to earth. When such fault current flows, it also causes the protective device (circuit breaker) to trip that circuit, thus removing the danger... (more)
Efficient use of electrical energy
Information from CBi-electric: low voltage 

A number of initiatives have begun to emerge from government (DME) and Eskom which include, among others, the Energy Conservation Scheme, Smart Systems and Solar Water Heating programmes... (more)
