基于搜索线圈电压和励磁电流特征分析的m相环形绕组无刷励磁机电枢故障可靠检测

In the operation of nuclear power plants, the fast, sensitive, and reliable diagnosis of rotating armature winding short circuit (AWSC) faults in m-phase toroidal brushless exciters (mPTBEs) is crucial. Traditional diagnosis approaches based on stator field current signature analysis (FCSA) are widely used on site due to their noninvasive nature. However, on-site operational experience has shown t...
