Abstract
A theoretical model is proposed to explain the statistics of electrical tree inception based on the geometry of the initiating electrode and the field variation around its surface. Numerical calculations show that the model is sufficient to describe qualitatively the observed features of both the time to inception distribution and the distribution of inception voltages (fields) obtained in ramp experiments. The implications of the model for the analysis of such experiments are discussed
