11 March 2008 - Power and automation technology group ABB, has won an order valued at $21m from Eskom, South Africa's national electricity provider, for series capacitor banks at Serumula on the Beta-Delphi 400kV transmission line, and Iziko on the Hydra-Poseidon 400kV transmission line.
The project forms part of the Southern Grid Strengthening Project in the Eastern Cape will ensure that customers in the Port Elizabeth area enjoy increased availability and quality of supply.
The Serumula and Iziko series capacitors will use the ABB MACH2 control and protection platform, which has the largest installed base for FACTS and HVDC controllers in Southern Africa. This will provide Eskom with increased built-in functionality, and possibilities for optional features to reduce equipment, maintenance and operation costs.
The installations would also use high-speed bypass switches from ABB, providing robust and reliable protection that will keep the MOV energy to a minimum, without spark gaps or complex semiconductor schemes. The project is scheduled to commence in January 2008 and is expected to be completed by mid 2009.
