In the considered experimental conditions, the average velocities of recorded streamers are of 2.4 km/s and 1.8 km/s for positive and negative streamers, respectively; these velocities correspond to the 2nd mode of streamers propagation. It is shown that the streamers present the fractal dimension D ; and the higher D is the bushier are the streamers (i.e. with high branch density). The positive streamers can have higher D than the negative ones, if they are bushier.}, type={Article}, title={Fractal dimensions analysis of branching streamers propagating in mineral oil}, URL={http://czasopisma.pan.pl/Content/124100/PDF/art08_i.pdf}, doi={10.24425/aee.2022.141677}, keywords={fractal analysis, lightning impulse voltage, mineral oil, streamers}, }
