Aiming at the problem of the corona discharge trigger electric filed threshold at different shapes of a metal tip, through the theoretical analysis of the electric field distribution near the surface of the conical tip and the ellipsoidal tip, and the laboratory simulation experiment, reached the following conclusion. The relationship between the value of corona current amplitude, the frequency and the tip’s radius of curvature is obtained; The corona discharge electric field threshold is relatively fixed and between 6.9382 kV/cm and 8.2824 kV/cm. The above relationship has a certain reference value in practical application and computer simulation.
