Assessment of industrial electrostatic hazards using finite-element electric field analysis
Assessment of industrial electrostatic hazards using finite-element electric field analysis
Charged clouds, generated in industrial processes, can lead to large values of space potential and electric field inside a vessel. Isolated masses of airborne liquid within can carry induced charge to the wall resulting in electrostatic discharges. Critical values of space potential can be found using a relationship between the jet safety factor and the material hazard coefficient. A computer package is described which allows complex space potential profiles and electric fields to be modelled for a prescribed space charge density. This allows the central space potential, a key indicator of electrostatic risk, to be evaluated. Examples are presented of two recent hazard investigations made by Wolfson Electrostatics.

Abstract
Charged clouds, generated in industrial processes, can lead to large values of space potential and electric field inside a vessel. Isolated masses of airborne liquid within can carry induced charge to the wall resulting in electrostatic discharges. Critical values of space potential can be found using a relationship between the jet safety factor and the material hazard coefficient. A computer package is described which allows complex space potential profiles and electric fields to be modelled for a prescribed space charge density. This allows the central space potential, a key indicator of electrostatic risk, to be evaluated. Examples are presented of two recent hazard investigations made by Wolfson Electrostatics.
