The interplay of treeing forms and aging phenomena

The effect of electrical tree structure on the energy spectrum of partial discharges is examined. This is shown for an exemplary electrical tree. It is argued that the dependence could be used, in reverse, to establish the dynamics of the aging process during electrical tree propagation. The nature of the energy dependence of partial discharges is illustrated for branchlike and bushlike trees, and an attempt is made to demonstrate the scaling method of approach to such processes.
