Stone Published in IEEE Transactions on Industry Applications IEEE standards and test procedures iwee 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. Use of AC and DC hipot tests iede assess stator winding insulation. The method is applied to determine core-end temperature when power is uprated to At that point, the temperature value will be compared to with the values obtained using finite elements method and multivariate regression.
