An interturn short-circuit fault in the stator winding of an electric machine, denoted as turn fault, has been recognized one most severe faults permanent magnet machines, which require a swift and reliable detection, order to implement appropriate mitigations. The asymmetry brought by is widely used for detection. However, similar features also emerge less high-resistance connection (HRC) may ...

A dynamic rotor interturn short circuit fault may occur during synchronous generator operation. However, there is no method to analyze the generator’s characteristics under and identify fault. In order solve this problem, a new analysis model creatively proposed through mathematical derivation. Firstly, vibration mechanical response magnetic pull excitation are theoretically analyzed. addition,...

the frequency response analysis (fra) test has been recognized as one of the sensitive tools available for detecting electrical and mechanical faults inside power transformers. however, there is still no universally systematic interpretation technique for these tests. many research efforts have employed different statistical criteria in order to aid the interpretative capability of the fra, but...

The lack of available measurements makes the detection electrical faults in rotating elements brushless synchronous machines particularly challenging. This paper presents a novel and fast method regarding interturn at field winding main machine, which is characterized because it non-intrusive its industrial application straightforward as does not require any additional equipment. built upon com...

Abstract Shaft voltage often exists in synchronous generators due to the assembly error or various faults after long‐term performance. The article investigates shaft characteristic under stator interturn short circuit (SISC) condition. Different from other studies, this mainly considers mapping relationship between amplitude–frequency characteristics of and SISC degrees. detailed expressions ar...
