Converter Transformer - an overview | ScienceDirect Topics station units with full size converters such as type 4 wind turbines and solar PV converter-transformer station units are modelled in the positive-sequence system as a current source. The current is provided by the manufacturer. The positive-sequence shunt impedance is assumed infinite.
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
