The interaction of HVDC converter with the saturation characteristic of converter transformer can lead to core saturation instability of converter transformer.
HVDC test is one of routine tests on the converter transformer.
Influence of converter transformer differential protection by harmonic in HVDC transmission system
Calculation and study for three-phase DC bias of converter transformer
Calculation of power-voltage curve for AC/DC hybrid power system considering converter transformer tap change and reactive power compensation
This paper studies the influence of converter transformer D-bridge zero sequence circulating current on valve short circuit protection.
The most important part of converter transformer insulation is the valve side outlet device, which consists of bushing and surrounding barrier system.
Applying voltage into the bushing tap method for preventive test of converter transformer value side bushing in HVDC, especially in the future for UHV, will have better practical value.
In view of harmonic which generated from the new-type HVDC analog system 12-pulse wave rectifiers and the inverter, designed passive filters system based on the new-type converter transformer.
