This paper presents the effect of the flashover on insulating surface under alternative current (AC) electric field stressed by humidity factor. It is obviously demonstrated about the insulator deterioration due to an ageing, partial discharge (PD) when it is used in services. Epoxy resin with the water droplets is brought to test by high voltage AC until flashover voltage levels. The flashover level on insulator surface depends on the volume and the number of the water droplets. The highest flashover voltage is 52.2 kV for the insulator surface without humidity, but the lowest voltage is 43.5 kV for water droplets of 1, 2, 3 and 4 drops (0.5, 1.0, 1.5 and 2.0 ml). Consequently, it leads to use the lower voltage respectively. The deformation of the water drop was oscillated, moved, elongated and broken up in to a several small drops on insulating surface. PD was the result of the flashover phenomena which causes the damage of the insulator. These results lead to protect the insulator surface under humidity effect from flashover phenomena.
