Power supplies
Corona
Electrical equipment; Power supplies
A non-self-sustaining discharge (sometimes visible) due to ionisation of the gas surrounding a conductor around which exists a voltage gradient exceeding a certain critical value for a gaseous ...
Plasma
Electrical equipment; Power supplies
A gaseous body of ions and electrons of sufficiently low density that considerable charge separation is possible. Because of the mobility of charge, a plasma is normally neutral and free of electric ...
Insulator
Electrical equipment; Power supplies

Flashover
Electrical equipment; Power supplies
A disruptive electrical discharge around or over the surface of a solid or liquid insulator.
Polymer
Electrical equipment; Power supplies
A compound formed by polymerization that results in the chemical union of monomers or the continued reaction between lower molecular weight polymers.
Electrode
Electrical equipment; Power supplies
A conductor, not necessarily metal, through which a current enters or leaves an electrolytic cell, arc, furnace, vacuum tube, gaseous discharge tube, or any conductor of the nonmetallic class.
