What are trichel pulses?
What are trichel pulses?
Trichel pulse is exactly a mode transition between low-current Townsend and high-current normal glow regime, two pulseless stages of negative corona with different operating conditions and ion flux threshold.
What is brush discharge on ship?
A brush discharge is a diffuse discharge from a single blunt conductor that is more rapid than corona and releases more energy. It is possible for a brush discharge to ignite gases and vapours.
How does a brush discharge work?
It is characterized by multiple luminous writhing sparks, plasma streamers composed of ionized air molecules, which repeatedly strike out from the electrode into the air, often with a crackling sound. The streamers spread out in a fan shape, giving it the appearance of a “brush”.
Why is it called corona discharge?
A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. A corona occurs at locations where the strength of the electric field (potential gradient) around a conductor exceeds the dielectric strength of the air.
What is onset voltage?
The onset voltage is practically independent of the gap length and in value is close to the onset of streamers under positive voltage for the same arrangement. The pulse frequency increases with the voltage and depends upon the radius of the cathode, the gap length and the pressure.
What is tanker terminology?
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine.
What is spark discharge?
Definition of spark discharge : an electric discharge accompanied by a spark : a disruptive discharge.
What is electric corona?
Corona Discharge (also known as the Corona Effect) is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor that is electrically charged. Corona discharge can cause an audible hissing or cracking noise as it ionizes the air around the conductors.
