Transmission networks of different high voltage levels are usually connected by autotransformers. These autotransformers are generally continuous flux types regulated from the HV or LV side. Some cases also require controlling the power flow between these networks. One such case is in Ghana, where the existing 161 kV transmission network is expanded by new 330 kV lines. A cost-effective and dependable solution selected by Ghana Authorities is the use of phase-shifting autotransformers. This article discusses the technical properties and design considerations of the 200 MVA 330/161 kV autotransformer installed in Ghana for this purpose in 2016.
