Abstract
Generally, the deterioration characteristics of a conductor affected by a forest fire can be analyzed through simulation of a forest fire and results of the simulation. However, there are little accomplishments of that kind of simulation applied to the power transmission, and there are not actual analyses for a sample exposed in a forest fire. This paper deals with the experimental results that apply to a new wire by artificial flame equipment because it is difficult to directly analyze the characteristic by a forest fire. Also, after an artificial flame is applied to a normal ACSR for various experimental conditions, changes of material and mechanical characteristics of the ACSR were analyzed by the surface inspection and tension load test of the ACSR. Then, the database will be made to made to predict the state of deteriorated wires by a forest fire using those two data, and data necessary to diagnose the life state of an ACSR affected by a forest fire will be given.
