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
• 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
• 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
