Alternator Rotor Inter-turn Short-Circuit Identification using FEM Based Learning
IFAC-PapersOnLine, 2015 The goal of this paper is to identify rotor inter-turn short-circuits of an alternator. The detection method is based on the analysis of a flux probe signal located in the air gap of the machine. Previous works have shown that pattern recognition can be applied to detect such a fault by using the experimental data as prototypes.
