The analysis algorithm named ACCESS was developed for galvanic sensor data, in order to qualitatively evaluate the corrosion rate. The analysis uses record of humidity along with the sensor data to extract outlier galvanic outputs that arise during rainfall. The quantitativeness of the analysis was verified using the field data observed in an exposure site and 19 transmission towers along a Japanese coastal area. The corrosion rates estimated from the sensor signals and measured using standard coupons were found to be in good agreement. The high corrosion season and its environmental features were extracted from the results of the short-term analysis of the corrosion rate, especially in the season of storm approach and snowfall.
