초록

In seashore, outdoor insulators are polluted due to salty wind and the pollution causes the flashover and failure of electric equipments. As well known, the pollution has a close relation with meteorological factors such as wind velocity, precipitation, wind direction, relative humidity, dew point, etc. In this paper we statistically analyzed the correlation between the pollution and the meteorological factors including snowfall and freezing. The multiple regression analysis was used for the statistical analysis; daily measured equivalent salt deposit density(dependent variable) and the meteorological data(independent variable) were used. From the results of this investigation, we verified the influence of snowfall and freezing on the ESDD, which has been overlooked in the preceding investigation.
