HVDC Classic converter transformers - Hitachi ABB Power Grids2020-11-14 · ABB has successfully developed the world's first 1,100 kV converter transformer with a power rating of 12,000 MW, breaking the record for the highest DC voltage levels ever. HVDC transmissions are used for transmission of power over long or very long distances, because it then becomes economically attractive over conventional AC lines.
Inspection, Test and Measurement Procedures for LV and MV ...· For older switchgear, a condition assessment should be performed to establish that the equipment remains in a suitable condition for further service. Partial discharge testing and infrared scanning can be used to obtain data on the performance of the insulation system and the integrity of the switchgear busbars and cable terminations.
