Abstract:The transmission tower is the most important supporting equipment on the overhead transmission line, which is related to the stable operation of the power system. The disaster of power transmission towers often brings corresponding losses to equipment assets. This paper analyzes the asset evaluation factors of transmission towers, uses fuzzy evaluation method to evaluate the asset value of transmission towers, and proposes a theoretical method for calculating the loss of transmission tower assets. Finally, a case description is given to verify the feasibility of the method.
