WebJun 11, 2024 · 1 Introduction and background A propagating brush discharge is a highly energetic type of electrostatic discharge which can occurs from a highly charged, relatively thin insulator, one side of which is in close contact with an earthed conductor. Britton [1] , amongst others, provides a more detailed description of the phenomenon. WebPropagating Brush Discharge – An energetic discharge caused by electrical breakdown across a dielectric layer having equal and opposite charges on the opposite sides of the layer. The two-sided charge is typically formed by charged plastic coating on a metal substrate, although proti wafers
