Topics dealing with the reduction of resistance in an insulator, including discharges, sparks and flashover

Subcategories

  • Arc discharges - an electrical breakdown of a gas that produces an ongoing plasma discharge, resulting from a current through a non-conducting medium such as air
  • Avalanche breakdown - a form of electric current multiplication that can create large currents in materials that are otherwise insulators
  • Corona - a discharge created by the ionization of a fluid surrounding an electrically-charged conductor
  • Dielectric breakdown - where a material has been stressed beyond its dielectric strength and part of the material goes from an insulating state to a conductive state
  • Discharges - any flow of electrons through a gas, liquid, or solid
  • Electrostatic discharge - static electricity that creates high voltages and can damage solid-state electrical equipment
  • Flashover - the near simultaneous ignition of most of the directly exposed combustible material in an enclosed area
  • Glow discharges - plasma formed by the passage of current above 100V through a gas, typically a noble gas
  • Partial discharges - or PD, the localized dielectric breakdown of insulation under high voltage
  • Sparks - a kind of electrostatic discharge that occurs when an electric field creates an ionized channel
  • Surface discharges - a kind of dielectric barrier discharge, which develops during an increase in applied voltage
  • Vacuum breakdown - where two uninsulated sources with different potentials induce a breakdown in a partial gas vacuum
