Greetings to Electricity+Control contributors and readers... and all the very best for 2012.
It will be difficult to ‘top' our 2011 spotlight, which was, of course, the Crown Publications and Electricity+Control 25th Anniversary. However, there is an interesting line-up of projects planned for this year and I encourage you all to become involved in some way. Keep an eye open for:
- E+C Spot On (our new online resource): To be launched in April 2012.
- Third edition of the Energy Efficiency Handbook (with a strong ‘EnviroFicient' component): To be published in October 2012.
- Best Writing Competition: All original, local articles published in 2012 will be entered into this competition. The winner of the 2011 competition won R10 000... it's certainly worth a try!
- Technology of the Future: Based on our regular topics, this special feature will appear in December 2012. How much of our lives will be automated? How many people will have access to internet by 2025? Will Sweden be the first oil-free country? The status of nuclear energy in 2050? Laser driven fusion energy? A hotel on the moon? Will we be texting by thinking (a little beyond me, I think)?
If you would like more information, please contact me.
Until next time...

Classic fieldbus to high-speed Ethernet: Communication plug connectors for industrial use
Cabling is decisive for the success and reliability of any system. Its topology, dimensioning rules and components must be precisely adapted to the production environment. The optimum plug connectors must always be used depending on the particular application area, transmission medium and environmental requirements.
Alternative motor starting solution
This article examines an alternative solution to starting large inline motors in order to minimise starting current and reduce associated voltage drop.
Income Tax Act-based allowances for energy efficiency: Part 2
Part 1 of this article was published in December 2011. It discussed the financial, technical and organisational support afforded by local government through the Income Tax Act of 1962 for energy efficiency tax incentives. Part 2 highlights the benefits of standardised energy efficiency practices; it ends with recommendations for organisations wishing to claim these incentives and individuals wishing to enter a career of verifying energy savings.
SANS 10313:2010 and IEC 62305 Parts 2 and 3
As a result of the substantial changes made in the lightning protection codes of practice in 2010 and the author's belief that many contractors are not implementing the required changes, the author's company has embarked on an education programme to inform consulting engineers of these new requirements. This article gives an outline of the basic requirements of the SANS and IEC codes of practice.
All inclusive pressure transmitters
The OEM transmitters described in this article are ‘embedded' in two different ways. Firstly, the sensor and the downstream electronics are ‘embedded' in the same housing, and secondly, the transmitter capsules themselves are ideally suited for embedding in application-specific systems. Depending on requirements, the output signal is standardised and temperature-compensated (rationmetric or digital).
Different types of UPS systems
This article clears up confusion in the marketplace about the different types of UPS systems and their characteristics - the information provided will lead to an educated decision as to the appropriate UPS topology for a given need.
