Northern Cape wind farms receive main transformers

The Northern Cape-based Khobab and Loeriesfontein wind farms announced last month that they had received their main transformer, which were transported by road from Johannesburg. The 160 MVA transformers are to be housed in substations, from where all the generated power from the wind farms will be transferred to the national grid.  “These transformers are responsible for increasing the voltage from 33 kV to 132 kV, which is the voltage required to transfer power to [State-owned utility] Eskom’s national grid,” explains Khobab wind farm project manager Kevin Foster.
