PPT-Electrical Insulating Materials (or Dielectrics) are materials in which electrostatic

Breakdown in Gaseous Insulation Gaseous dielectrics in practice are not free of electrically charged particles including free electrons The electrons which may be caused by irradiation or field emission can lead to a breakdown process to be initiated . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir The Electrostatic Equations If we consider the case (i.e., constant with time) of Maxwell .
