Abstract : The effects of pressure and electric field strength on corona are presented with the goal of showing how corona can be produced under favorable to the EFD process. Unique properties of the two-dimensional electric field are shown along with their effects on corona charge production. Experiments are described which compare the performance of various corona electrodes in the amount of current they can produce under similar conditions, as well as the effects of pressure and relative humidity levels on corona current. The effect of an electric distribution in producing a non-uniform electric field is shown. One electrode shape, the flat-edged corona disc, was found to be superior to the others in the amount of current produced, durability, attractor voltage required, and anticipated operation at very high pressure levels.
