A total of six series capacitors are coming on line in 2012 in the 765 kV national grid in South Africa, supplied and installed by ABB.

For many years, Gerdau in Charlotte has been operating an EAF of continuous scrap charging type in their industrial process. In this type of furnace, the cold scrap is fed into the side of the furnace from a conveyor system where it is immersed into liquid steel, with continuous melting taking place (Fig. 1).

The first hybrid static synchronous compensator for dynamic voltage stabilisation in Germany

ABB has installed two series capacitors in Fingrid’s 400 kV grid to strenghten the power transmission capacity in northern Finland and to assure power system security. The series capacitors both went on line in 2009.

A Static Var Compensator (SVC) rated at 75 Mvar inductive to 150 Mvar capacitive (-75/+150 Mvar) at 230 kV, supplied and installed by ABB, has gone into operation at the Extremoz substation belonging to Chesf, a Brazilian transmission and generation utility located in the state of Rio Grande do Norte in Northeastern Brazil.

Hydro One is the largest electricity transmission and distribution company in the province of Ontario, Canada. The Company owns and operates substantially all of Ontario’s electricity transmission system, accounting for approximately 96.6% of Ontario’s transmission capacity.

Evron is a substation in the French rail system between Paris and Rennes in Western France, fed from the RTE national power grid. An SVC Light®, supplied by ABB, is operated by SNCF (the French railway company) for dynamic balancing of asymmetry between phases caused by the mode of traction feeding, take-off of power between two phases in the three-phase grid.
