Abstract
The development of an electrical breakdown in water with a conductivity of 255 µS/cm under the effect of ultrasonic waves for the “tip–pin” geometry of electrodes with an interelectrode gap of 8 mm is experimentally studied. It is found that at the same voltage close to the minimum breakdown voltage the probability of the breakdown initiation and discharge closure of the gap increases by two times when exposed to ultrasound without cavitation, and the time of the pre-breakdown stage is reduced compared to the breakdown without ultrasound.
