Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.
Electrostatic discharge while fueling with gasoline is a present danger at gas stations. [24] Fires have also been started at airports while refueling aircraft with kerosene. New grounding technologies, the use of conducting materials, and the addition of anti-static additives help to prevent or safely dissipate the buildup of static electricity.
An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. [1] ESD commonly also stands for electrostatic discharge.
This is the ideal shape to minimize leakage and corona discharge, so the Van de Graaff generator can produce the greatest voltage. This is why the Van de Graaff design has been used for all electrostatic particle accelerators. In general, the larger the diameter and the smoother the sphere is, the higher the voltage that can be achieved.
Corona discharge — occurs at sharp points and edges (radius < 1 mm). It is a uniform ionization (glow discharge) visible as a dim stationary blue glow, fading out as it extends from the conductor. Brush discharge — occurs at a curved electrode (radius between 5 and 50 mm) [3] in the vicinity of a flat electrode. It consists of a short ...
An electric charge near a metal object causes the mobile charges in the metal to separate. If the external charge is positive as shown, negative charges (blue) are attracted and move to the surface of the object facing the external charge, positive charges (red) are repelled and move to the surface of the object facing away.
Electrostatic discharge (ESD) is a subclass of electrical overstress and may cause immediate device failure, permanent parameter shifts and latent damage causing increased degradation rate. It has at least one of three components, localized heat generation, high current density and high electric field gradient; prolonged presence of currents of ...
A hose reel is a cylindrical spindle made of either metal, fiberglass, or plastic and is used for storing a hose. The most common styles of hose reels are spring driven (which is self retracting), hand crank, or motor driven. Hose reels are categorized by the diameter and length of the hose they hold, the pressure rating and the
