Abstract :
The effect of the wind velocity on a corona-point electrode in a point-to-plane arrangement is presented in this paper. An important relationship between the wind velocity, the electric field and the magnitude of the corona current was observed. The experiment is performed in a shielded room at the atmospheric pressure and temperature of Bogotá, Colombia (2.600 m over sea level). The wind velocity was controlled.
