Abstract :This paper reports on insulator contamination, which threatens the external insulation of electric power systems, especially on salt contamination characteristics on the insulator surface and topographyical shielding effects during and after a typhoon strike. Typhoon is one of the severest meteorological conditions for insulation of the surface of insulators on Okinawa Island. Insulator contamination has been measured for the last twenty years at ninety-one locations in the Island where pilot insulators were set up. The maximum contamination of ninety sites among ninety-one locations was due to typhoon's assaults. Twenty-five sites were subjected to special contamination area, where the contaminations of the insulators were over 0.35mg/cm^2 and forty-nine sites to very serious contamination area, where the contaminations of 0.12mg/cm^2 to 0.35mg/cm^2 were recorded.
