摘要
Abstract
Solar magnetic storm, monopole or asymmetric operation of DC transmission may cause DC mag-netic bias. The actual test indicates that the monopole operation mode of DC transmission causes severe DC bias in neutral-grounded transformers near ground electrodes and DC magnetic bias exerts derivative influence on transformers such as increase of noise, aggravation of vibration and abnormal harmonic and so on.关键词
