Copper association launches Africa Electricity Programme
by Evert Swanepoel, Copper Development Association Africa 

Copper is clearly the best electrical conductor at an affordable price. With an electrical conductivity of 5,97 x 107 S/m, it is an indispensable material for achieving a compact installation with high energy efficiency... (more) 
Contactless energy transfer for drives
Information from SEW Eurodrive 

Plant engineers and production system designers view electrical wiring as cumbersome and costly. The advent of "contactless energy transfer" could eliminate these problems... (more) 
 
Vector Inbox: Justifying the LED hype
This month's winning letter from Johann Schleritzko, Beka

I appreciate Howard Page's comprehensive letter ("Too much LED hype!" Vector, March 2013), since it reflects the comments one often comes across when discussing LED technologies with clients. I certainly agree that some claims, when promoting LED

Many lighting companies have an incorrect view of how the human eye handles light. This can lead to inefficient lighting, misconceptions and conflicting rules about the appropriate colour of light and light levels... (more) 
Extending the life of existing switchgear
by Hal Theobald, Schneider Electric

Electrical equipment manufacturers generally require annual maintenance for power circuit breakers to ensure proper operation and to maintain equipment warranties. This maintenance consists of cleaning and lubrication of the primary and secondary disconnects, racking mechanisms and cell interlocks... (more) 
Selecting electronic power meters
by Rick Schlobohm, GE

These meters are often viewed as an unnecessary expense but basic, single point metering can cost as little as 1% of the total project while providing significant ongoing benefits to engineers modifying or upgrading their gear... (more)

Smart metering (SM) systems can support various aspects of electricity distribution management, but it is important to understand the additional functionality of SM systems and to establish whether they meet the requirements for Africa... (more) 
Paper insulated cables for mining, petrochemicals, Ex applications
Information from Aberdare Cables 

Paper insulated cables have been in use longer than any other type of cable insulation and are still a favourite with engineers. When selected properly and installed correctly, paper insulated cables can be relied upon to provide satisfactory performance... (more) 
Switchgear reliability, personnel safety solutions
Information from Eaton 

Advances in materials science, designing and manufacturing process made MV switchgear much more reliable. In spite of this, insulation failures continue to happen, often resulting in catastrophic equipment damage. Periodical maintenance tests can still leave switchgear in virtually unknown condition...
