REASONS FOR THE DISPERSION OF BREAKDOWN VOLTAGES IN SF6
W. Hauschild et W. Mosch.Dresden Technical University, Department for Electrical Engineering Dresden, G.D.R.
Abstract
The breakdown in SF6 is a stochastic process, on the one hand because of the random development of electron avalanch [1] [2] [3], on the other hand because of random influences on the electrostatic field by micro-particles, micro-protrusions, or micro-discharges [1] [2] [3] [4] [5]. It is investigated which of the random influences causes the dispersion of the breakdown voltage at different kinds of the stressing voltage.
