Jc. Fothergill et al., A DISCHARGE-AVALANCHE THEORY FOR THE PROPAGATION OF ELECTRICAL TREES - A PHYSICAL BASIS FOR THEIR VOLTAGE-DEPENDENCE, IEEE transactions on dielectrics and electrical insulation, 1(3), 1994, pp. 474-486
The voltage dependence of electrical tree propagation from both recess
ed voids and embedded needle electrodes is described in terms of a qua
ntitatively expressed physical model. Voltage dependent changes in the
fractal dimension of the trees are used to explain the nonmonotonic b
ehavior observed in the embedded needle geometry. The relationship of
the model to inverse power law and 'Z' lifeline characteristics is bri
efly discussed.
