title = "EFFECT OF CLAMPING PRESSURE ON TRANSFORMER WINDING VIBRATION",
abstract = "In this paper, the effect of clamping pressure on the vibration of transformer winding is examined. For a steady-state force excitation at 100 Hz, the spatial variations of the amplitude and phase of the winding increase as the clamping pressure decreases. This result is consistent with the previously observed increase of spatial variation in the phase of power transformers with mechanical faults in the windings. Further measurement of the frequency response function of a winding structure reveals the mechanisms involved in the increased variation for transformers with loosened clamping. It is shown that reduction of the clamping pressure causes a shift of higher-order resonance modes towards the low-frequency region. The increased participation of those modes in the forced vibration response results in the increased spatial variation in the measured amplitude and phase.",
