Switchgear - an overview | ScienceDirect Topics HV transmission switchgear. HV transmission switchgear is used within substations to control the flow of large quantities of electric power within an electrical network. It may operate at rated voltages of 145–800 kV, with normal load currents of up to 4 kA and short-circuit currents of up to 80 kA.
HVDC converter station - Wikipedia HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: . three-phase alternating current switch gear

What is an HVDC (High Voltage Direct ... - ELECTRICAL STUDY HVDC converter transformer can be built as three-phase units or as single-phase units depending on voltage and power rating. When built as three-phase transformers there is generally one unit with the valve winding arranged for star connection and the other unit for delta connection. In single-phase design, the two valve windings are generally built on the same transformer unit.
