要約(英語): Overhead transmission lines are exposed to the natural environment, and many electrical faults are caused by influences of the external environment such as lightning and snow. In addition, birds such as crows and animals such as monkeys, snakes, and bears also cause electrical faults. The material of a crow's nest, which is often made of metallic materials such as wire or hangers, has been one of the causes of electrical faults. As a countermeasure against the crow's nesting, warning sounds and flashes that crows must dislike, objects that move irregularly by springs, artificial birds that imitate the natural enemies of crows such as falcons, and the corpses of crows are have been experimentally installed to transmission towers, however, there are few quantitative evaluation about these, and the effect has been limited. Moreover, it has been difficult to evaluate the effectiveness of these countermeasures clearly. Therefore, this paper focuses on the decreasing of the electrical faults by decreasing of the crow's nesting and describes the characteristics of nesting behavior of crows at 66-154kV transmission towers and effectiveness of crow nesting prevention products.
