A sometimes glowing discharge on the surface of one or more conductors, which results from a buildup of excess electrons on a conductive surface at high voltage, a partial electric breakdown in a gas, as in the air surrounding a wire at high potential.
a method for producing ozone, by utilizing high voltage arcing to convert oxygen (O) into ozone (O). Refer to the listing for Ozone for more information.
an electrical discharge accompanied by ionization of surrounding atmosphere
an electrical discharge brought on by the ionization of gas surrounding a conductor , which occurs when the potential gradient exceeds a certain vale but is not sufficient to cause sparking
a result of ionization in the gas around a high-voltage source
A localized cold discharge in air which forms around grounded objects producing an enhancement in electric field strength to allow ionization growth. Called St. Elmos's Fire by ancient mariners. Precedes an arc or spark.
a luminous discharge which occurs when the applied voltage is high enough (5000 volts or more) to cause partial ionization of the surrounding gas
The corona discharge is a discharge phenomenon observed when high voltage is applied to pointed conductive objects like a needle. When the corona discharge occurs, the discharged electrons generate atmospheric ions around the tip of the needle by colliding with molecules in the air with great force. The corona discharge method static eliminator was developed to eliminate static by exploiting this phenomenon.
The discharge of electricity causing a faint glow adjacent to the surface of an electrical conductor and, similarly, adjacent to the dielectrics in an ozone generator during ozone production.
An electrical surface treatment that encourages oxidation through ionisation of a surface to reduce surface tension and improve ink adhesion.
In electricity, a corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor, which occurs when the potential gradient exceeds a certain value, but conditions are insufficient to cause complete electrical breakdown or arcing.
