Abstract
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.
