Electrical Breakdown Between Spheres

Application ID: 74081

This model verifies that the onset of streamer formation between two spheres separated by atmospheric pressure dry air at a distance of 2cm occurs at 51.8kV. The electrical breakdown is detected by integrating Townsend coefficients along the electric field lines between the two spheres. Once the integrated Townsend coefficient reaches a certain threshold, a streamer will form creating a short circuit.

This model example illustrates applications of this type that would nominally be built using the following products:
