Aeolian Noise from High Voltage Insulators

In this paper, a review is attempted for understanding of aeolian noise from high voltage insulators and their aerodynamic noise characteristics were investigated using the low noise wind tunnel. The noise from the insulators was dependent upon the wind speed and their orientation relative to the wind direction. The noise spectrum revealed sharp peak which was found the cavity resonance frequency.
