Sultartangi Station back on-line

November 12, 2008
The station is producing electricity at half capacity which increases the reliability and supply of electricity for the coming winter.
As previously announced, there have been serious malfunctions in the transformers of the Sultartangi Station both this year and at the close of last year. The basic cause of the malfunctions has now been traced to electrical insulating oils applied to the transformers when they were built. Certain substances in the oil have caused corrosion in the insulation. The corrosion had an effect whereby over-voltage that the transformers were supposed to be able to handle caused serious damages.
In recent years, it has been revealed that several transformers worldwide of the same age have suffered similar malfunctions. The other transformer at the Sultartangi Station will be repaired overseas by its manufacturer and it is hoped that it will be possible to bring it online by the middle of 2009.
Due to uncertainties regarding the lifetime of the transformers after repair, a decision has been made to purchase new transformers to replace the old ones. The purchase has been finalised and it is anticipated that the new transformers will be brought online in October 2009 and February 2010.
