Faulty transformer en route from Namibia to S. Africa for repairs
Namibia: Namibian energy company NamPower said one of the four transformers that were commissioned with the Zambezi Link Interconnector in 2010 is on the way to Eskom-Rotek Industries in Johannesburg, South Africa for repairs.
The 175-ton transformer was stationed at Gerus Substation near Otjiwarongo, and connected the HVDC system to the rest of the NamPower system, reports Namibia Economist.
Internal transformer faults were detected through the regular maintenance programme, so NamPower de-energised the transformer to prevent further damage to the unit.
According to the utility, the transformer that remained at the station is of the same capacity and is be able to handle the load transfers required until the other unit is repaired and back in service, which is expected to be by April 2019.
