Generation and Control of Static Electricity

Static electricity is generated by liquids flowing through pipes, and in mixing, pouring, pumping, filtering, or agitating liquids. The rate of generation is influenced by the conductive of the liquids, the amount of turbulence in the liquid, the interfacial surface area between the liquids and other surfaces, liquid velocity, and the presence of impurities.

Sources of Static Grounding and Methods to Control

Methods of Static Control. In addition to being dependent on the charge generation rate, charge accumulation is a function of the resistance of the path by which charges dissipate. Within the material, the dissipation of static electricity is dependent on the material’s “conductivity.”

Static Electricity Hazards, Generation and Grounding in ...

Overview. The generation of static electricity cannot be stopped, but its rate of accumulation and dispersal can be controlled with proper engineering of machinery, pipes, and filtration systems, as well as by utilizing proper bonding and grounding equipment.

Electrostatic generator - Wikipedia

An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current.The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its behavior and often confused ...

Fraser Anti Static Techniques | HOW IS STATIC …

how is static electricity generated The main causes of static electricity are: Contact & Separation between two materials – including friction, travelling over rollers etc. Rapid heat change e.g. material going through an oven, or polymers during injection moulding.

Danger And Control Of Static Electricity Buildup

A simpler device is the static comb, which does not use electricity at all. It consists of a metallic bar with a row of sharp points projecting from it and bonded to ground. When this device is placed near the charged surface, the electric stress due to accumulation of charge near the sharp points causes ionization and helps to drain the charge from the surface.
