Comparative study of dual 3‐phase permanent magnet machines with coil span of two slot‐pitches
IET Electric Power Applications, Volume 16, Issue 12, Page 1426-1438, December 2022., 2022 Abstract In this study, the electromagnetic performances of dual 3‐phase permanent magnet (PM) machines with coil span of two slot‐pitches are comparatively investigated. It mainly focuses on two PM machines with different slot/pole number combinations (Ns/2p), that is, the 24‐slot/10‐pole and 24‐slot/14‐pole machines (2p = Ns/2 ± 2).

IET Generation, Transmission &Distribution, Volume 16, Issue 23, Page 4750-4760, December 2022., 2022 Abstract Converter transformer inter‐tap short‐circuit faults in on‐load tap changers have occurred successively in recent years, resulting in severe accidents and enormous losses. Due to the lack of an effective model and credible arc‐in‐oil conductance parameters, related fault analysis has remained a challenge.
