The asymmetric Stockbridge vibration damper is commonly employed in overhead power cables to mitigate Aeolian vibration, which is the oscillation of conductor cables within the 3–150 Hz frequency range. The damper's effectiveness is determined by its resonant frequencies, which increase power dissipation to exceed the wind-induced power input. While the basic symmetric Stockbridge damper has two resonant frequencies, the asymmetric version can exhibit up to four. Previous studies have shown that changes in the counterweight's geometry can increase the natural frequencies. This paper presents experiments on a modified asymmetric damper and uses an analytical model from Vaja et al. (2018), to confirm their findings. employed in overhead transmission lines to mitigate Aeolian vibration
