一种基于高频中性点对地电压的匝间短路故障检测新策略

With the increasing application of permanent magnet (PM) machines, the drive reliability should be guaranteed for safety-critical applications. As a severe stator winding short-circuit fault, turn fault causes excessive fault current and affects the machine's stable operation. Thus, this article proposes a new turn fault detection strategy based on high-frequency (HF) neutral-to-ground voltages (N...
