Evaluation of Dynamic and Static Eccentric Faults in Turbo Generator

Abstract: Rotor eccentricity is a common fault in turbo generators, but there is currently no effective means of evaluating the eccentric state of the generators. In this article, the air‐gap permeance method was used to analyze the influence of rotor eccentricity on the no‐load main magnetic field, and the installation of U‐type detection coils within the stator core was proposed. Using this method, the dynamic eccentricity level can be measured by detecting the 2nd harmonic amplitude of the coil‐induced voltage, and t… Show more
