Half-cycle circuit breaker for rural smart grids minimises operating costs of feeder, spur lines
by Dr. Brett Watson, Dirk Scheerer, and Benjamin Gischke, Siemens
Rural electricity distribution is less reliable and more expensive to operate than urban networks and generates less revenue. Long overhead line lengths, inherent high fault frequency and the often considerable time taken to find and access faults result in long outage durations, poor regulatory performance and, often, financial penalties...

Demystifying the smart grid
by Stuart Michie, ABB
The principles of the technology of today's power grids have not changed significantly in the past 100 years. Electricity is a product that has to be generated at the time of need. The level of power generation is set to match the instantaneous demand. With the constraints in power resources, this has to change, hence the development of the smart grid... (more) |
When is smart metering really smart? by Kobus van den Berg, Aurecon
Smart metering (SM) systems are rolled out at a high rate internationally for various reasons. It is however true that SM as a component of smart grids will play a significant role in the electricity distribution industry to enhance energy efficiency and support revenue management... ( more)
