Schematic diagram of ion movement in half an AC cycle. (a) When the voltage is zero, the space charge distribution diagram is around the conductor. (b) Schematic diagram of space charge movement around the conductor after the corona discharge begins. (c) Schematic diagram of the space charge movement around the conductor after the corona discharge stops.
