Abstract

In this paper, there analyzed the UV behavior and detection images due to corona discharge of insulators at 22.9kV. As the results, the shapes of UV detection images are jellyfish, sunflower, and amoeba type. Generally, the jellyfish and sunflower type appeared in air discharge. In surface discharge, Amoeba is generated. Also, there are classified 8 patterns such as sunflower A or B, jellyfish A or B, amoeba A, B, C, D. This method of the facilities assessment has an immediate effect in the field.
