Webb is the breakdown voltage of the air gap and L is length of the di scharge. k is the correction for humid ity; and E s0 is the average electric field of the positive streamer at standard reference atmosphere. It is inte nded to determine, by the value of G, how much a breakdown will be contributed by streamer at the given gap. computer networking clip artWebJul 8, 2002 · Maybe I can add some. As the altitude increases, there is less air, which acts as an insulator. Dry and clean air is actually quite a good insulator. Dirt and moisture degrade the insulation (air). There is a curve that shows the insulating qualities of air vs. pressure. As the air presure drops, the breakdown voltage drops. eco chic bedfordWebMay 15, 2012 · The breakdown voltage curves for dry (black triangles), ambient (blue circles) and synthetic air (red crosses) for the interelectrode separation of 100 μ m are compared in Fig. 2.
