Monopolar Corona on Bundle Wires as Influenced by Wind

The measured corona current contributed by each subwire in various laboratory-size bundle models and the total corona current change with wind over a wide range of applied voltages are described. The lateral spacial distribution of the time-average value of windblown corona current over the ground plate is measured for different applied voltages and different bundle geometries. The obtained results are compared to previous findings and to theories of corona discharge.
