Abstract :
50Hz breakdown voltages have been measured for rod-rod gaps of 0.1¿1.5m, and for point-point gaps of 0.1¿0.4m, at different air temperatures and at about atmospheric pressure. The density-correction factor K derived from the measurements is a linear function of air density at a constant gap length. For a constant air density, K is larger for a greater gap length; K is also larger for a point-point gap than for a rod-rod gap of the same gap length.
