The purpose of this paper is to analyze the correlation relationship between the salt contamination environment and the actual damage to electric power distribution equipment caused by two typhoons, 2012 typhoon No. 4 (T1204) and 2011 typhoon No. 15 (T1115). T1204 caused salt contamination damage to voltage–current transformers (VCTs), while the T1115 caused no damage to VCTs installed in a same target area. In this paper, the salt contamination environment during the two typhoons, which includes the maximum wind speed, the accumulated rainfall, and the Na + flux, is evaluated by a weather reproduction simulation to discuss the causal relationship between the salt contamination environment and the VCT damage. A damage evaluation model is proposed to evaluate the salt‐induced damage risk potential of the VCT for reasonable restoration activity.
