Report from S&T Project 1862: Dielectric Frequency Response of Generator Stator Windings

Dielectric Frequency Response (DFR) testing has become an accepted test for analyzing oil filled power transformer insulation which has sparked interest in the rotating machine community. DFR testing provides similar test points compared to traditional test methods but performed at much lower test voltages. This study’s primary goal was to determine if DFR testing could provide equivalent test results to traditional test methods. Results from the study are inconsistent with respect to aligning with traditional rotating machine test methods. At times the results would correlate well, and others would differ greatly. Additional data points and study would be required to determine if these inconsistencies continue, the data correlates, or differs from traditional methods.
