Numerical values of the mean field in oil required for direct or burst breakdown modes are derived from the experiments. We find that it is the instability condition, derived from a relation between the minimum Laplacian field in the gap and the local streamer body field (which we relate to the streamer sustaining field), that is sufficient for determining the spark threshold thereby yielding a breakdown criterion. of gradually increasing curvature.
