Tesla coil
electrical resonant transformer circuit invented by Nikola Tesla
corona discharge
electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged
electrostatic discharge
sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown
Kirlian photography
photographic technique used to capture electrical coronal discharges
electric spark
kind of electrical discharge
induction coil
type of electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply
electrical breakdown
physical phenomenon where applying sufficient voltage causes an electrical insulator to become conductive
spark gap
gap between two electrodes that is used for generating sparks
Lichtenberg figure
A branching electric discharge that sometimes appears on the surface or in the interior of insulating materials
avalanche breakdown
phenomenon that can occur in both insulating and semiconducting materials
John Sealy Townsend
Irish mathematical physicist (1868–1957)
breakdown voltage
the minimum voltage that causes an insulator to become electrically conductive
Paschen's law
physical law about electrical discharge in gases
partial discharge
localized dielectric breakdown (DB) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress, which does not bridge the space between two conductors
Zener effect
type of electrical breakdown in a reverse-biased diode
Geiger-Müller tube
sensing element of a Geiger counter instrument
electron avalanche
process in which a number of free electrons in a transmission medium are subjected to strong acceleration by an electric field and subsequently collide with other atoms of the medium, thereby ionizing them (impact ionization)
voltage regulator tube
gas-filled tube for voltage regulation employing either glow or corona discharge
electrical treeing
electrical pre-breakdown phenomenon in solid insulation
corona ring
component of the electrical power system
Comparative Tracking Index
for measuring the electrical breakdown (tracking) properties of insulating material
townsend
physical unit of reduced electric field
