Just what is "sustainable development"? 
by Philip Lloyd, Cape Peninsula University of Technology 
 
Prof. Philip Lloyd
If there is one thing on which everyone agrees, it is sustainable development.  Yes, we all want development, and yes, we are all as green as each other and want development to be "sustainable". But when you scratch the surface, you soon discover people talking past each other.  How can chopping down trees, or digging up gold, be sustainable?... (more)

Water blocking in MV XLPE cables
Information from Aberdare Cables 
 
The penetration of water or the presence of moisture in XLPE cables is a serious problem associated with the lifespan of cables under the influence of high electrical stresses. XLPE insulated cables which are designed to operate at 600 to 1000 V require insulation thicknesses well above those required purely for electrical performance... (more)
by B Gittins, NSW Department of Trade and Investment, Australia
 
An underground mine was evacuated after a fault occurred involving the three-phase and ground on the 33 kV overhead line on the mine surface. While the initial fault cleared quickly, it appears to have led to a so-called "cross country fault" in the 33 kV reticulation system... (more)
