A-C Corona in Foul Weather I-Above Freezing Point

After a brief survey of water appearance in the close-to-ground layer of atmosphere, behavior of water drops in the electric field is analyzed and the mechanism of streamer formations shown. Water influence, causing corona increase, has two components: (1) discharges between conductor and passing drops and (2) streamers produced by water presence on the conductor. Results of some attempts to limit streamer formation when water is present on the conductor are reported.
