Abstract: Vibration frequency response analysis (VFRA) was used to test the same winding under the same state at different times. The winding of phase C was artificially made faults of pressboard missing and winding radial deformation. The experimental data show that the VFRA can effectively detect the faults of windings’ deformation and the results are repetitive. Compared with shortcircuit reactance measurement, the VFRA is more sensitive.
