Introduction to the special section on advances in diagnosis for electrical machines, power electronics, and drives - Part I.

Even if modern diagnostic techniques in power electrical engineering are considered as mature, there are still innovations to be published. Therefore, among the 188 papers submitted to this Special Section, 28 have been selected to be published in two parts. This Introduction is related to the first 14 selected papers, which have been divided into three topics dealing with: electrical machines failures detection with bearings (four papers), backlash phenomena (one paper), shaft trajectories (one paper), and winding short circuits (one paper); adjustable-speed drives with permanent-magnet synchronous machines (PMSMs) winding short circuits (one paper), drive sensors (one paper), prognosis (one paper), inverter open-circuit detection (one paper), and multiphase induction motors (one paper); power systems (one paper) and transformers (one paper) particular fault detection.
