| Abstract: | This paper analyzes the impacts of long-time DC biasing magnetism on 500 kV transformers in Jiangsu Power Network. Long-timeDC biasing magnetism caused by DC transmission line makes significant impacts on noise, harmonics, losses, and temperature rise of the coreand windings of transformers. According to theoretical analysis and calculations of testing data, the impacts of long-time DC biasingmagnetism on power network equipments are analyzed. |
| Keywords: | DC biasing magnetism transformer noise temperature rise magnetic storm |
