Vibration of a transmission-line conductor is set up by corona discharge on water drops hanging beneath the conductor under rainy weather. This corona-induced vibration of a transmission-line conductor has become more serious problem owing to the rise of transmission voltage. The purpose of this study is to make the mechanism of corona-induced vibration clear. In this experiment, vibration waveform and corona current waveform were recorded. Moreover, photographs of a water drop were taken. By means of those waveforms, a peak value of corona current, vibration amplitude, outbreak frequency of corona current pulse and a phase lag angle between corona current and vibration were measured. The main results are summarized as follows
