Current distribution of AC surface discharges and associated chemistry
It is shown that AC discharges propagating at an air/dielectric interface, though of planar structure, behave, till a critical voltage V crit , as corona discharges in an air gap, with similar propagation fields for the filamentary discharge components and similar glow components. This leads to cons...

In return, the surface gives its energy excess back to the discharge, so opening the way, on the surface, to leader-like discharges of higher conductivity, needing about 10 times lower fields to propagate. |
