ABSTRACT Electrical breakdown at the edges of sessile water droplets on a horizontal, insulating surface subject to high AC electrical stress has been studied experimentally. The behaviour of the water droplets under these conditions has been examined using a high-speed video camera and by detecting electrically partial discharge activity. Different modes of droplet vibration have been observed, some of which lead to transient changes in droplet contact angle at the insulator surface with concomitant changes in the electric field in the vicinity of the triple junction. These field effects have been calculated and their significance on partial electrical discharges discussed. Lateral spreading of water droplets has also been observed. It is considered this spreading is associated with the vibration and with the partial discharge activity.
