This paper is a continuation of a series of experiments that studied a pulsed discharge that propagates above a liquid surface. A detailed study of the influence of a dielectric barrier on the nature of the propagation of a pulsed discharge above a water surface was conducted. It was shown that the presence of barriers leads to an increase in the initial voltage pulse that is required for discharge propagation. Along with this, a decisive role was played by the barrier that was nearest to the point of the electrode.
