The development of an arc along the polluted surface depends to a great extent on the electric field of streamer at the arc head and the current densities in the wet polluted layer and arc. To investigate the parameters that vary depending on the arc length during the development of an arc, a simplified model of development arc along the polluted surface was established. Based on the numerical calculation of characteristic quantities of electric field and current density in the simplified model, the influencing factors on the development of arc were investigated.
