Self-organized criticality in electrical treeing

Self-organized criticality aspects of electrical treeing in solid dielectric under ac voltage are considered. The sandpile model of self-organized criticality is modified to describe partial discharge activity from electrical treeing. A comparison of avalanche statistics simulated by the modified sa...

Description
Summary:Self-organized criticality aspects of electrical treeing in solid dielectric under ac voltage are considered. The sandpile model of self-organized criticality is modified to describe partial discharge activity from electrical treeing. A comparison of avalanche statistics simulated by the modified sandpile model and partial discharge data obtained in experiments confirms the existence of self-organized criticality in electrical treeing.
