High – voltage DC tests for evaluating stator winding insulation: Understanding water treeing mechanisms in the development of diagnostic test methods.
This paper has 48 citations. The end region of a stator is the most sensitive part to overheating. Dhirani, Electrical Insulation for Rotating Machines. Showing of 39 extracted citations.
The calculation of magnetic fields, the evaluation of eddy-current losses and the determination of loss-derived temperature increases, are challenging problems requiring the use of simulation methods. Diagnostic tests Interpretation logic Iewe.
The method is applied to determine core-end temperature when power is uprated to BlanquezCarlos A. At that point, the temperature value will be compared to with the values obtained using finite elements method and multivariate regression.

World Journal of Engineering and TechnologyVol. Power uprates pose a threat to electrical generators due to possible parasite effects that can develop potential failure sources ieeee catastrophic consequences in most cases. The most usual methodology is the finite element method, or linear regression. The mathematical model developed was based on an artificial intelligence technique, more specifically neural networks. Uniform stepgraded stepand ramped test methods.
References Publications referenced by this paper. In that sense, it is important to pay close attention to overheating, which results from excessive system losses and cooling system inefficiency.

Stone Published in IEEE Transactions on Industry Applications IEEE standards and test procedures are widely used by motor and generator vendors and users to commission windings in new machines, as well as evaluate the condition of the winding insulation in operating machines. Showing of 7 references. Until recent revisions, the basic procedures and standards in use were written over 25 years ago. Examples of stator winding partial discharges due to inverter drives.
