HVDC Converter Transformers

High Voltage Direct Current (HVDC) systems allow the transmission of energy over long distances and are also solutions for interconnection of networks with different characteristics and frequencies. To this end, GE offers a wide range of dedicated special transformers that enable efficient and reliable electric power transmission.

Direct current transformer components, usually superimposed on the AC ones, appear both during service and during factory testing, and generate high levels of stress on the valve windings that are connected to the rectifier bridge. The design and manufacture of HVDC converter transformers requires a fine mastery of insulation structure. The high harmonic content of the load current also demands a very specific knowledge of thermal design. GE is an expert in this field.

Ratings include 500 MVA and voltage levels up to 800 kV.
