通过分析励磁机电枢电流进行旋转整流器开路故障诊断

Based on the differences between waveforms of asynchronous exciter three-phase armature currents with the rotating rectifier under various working conditions (healthy and open-circuit conditions), a fault diagnosis method of rotating rectifier is proposed in this article. To describe these differences, the conceptions of ratio, residual, and sum are defined, and corresponding calculation functions...
