Abstract The aging phenomenon of transmission lines poses a serious threat to its safety and stable operation. Condition based maintenance is gradually replacing the traditional periodic maintenance as an important means of transmission line maintenance due to its strong targeting, good economy, excellent maintenance effect and other characteristics. As an indispensable basic step in the process of condition based maintenance, state assessment is based on the analysis of equipment condition index data, which can accurately reflect the health status of the equipment, and discover potential faults in a timely manner. To this end, this paper proposes a transmission line condition based maintenance method. The aging fault prediction model is built through the assessment of the transmission line components of the health index. The probability of aging faults and their consequences are quantified to achieve the probability of aging faults year by year prediction. The risk of aging phenomenon from the level of economic loss is quantitative analyzed. The condition management and risk assessment are combined to provide decision support for managers to formulate overhaul, technical improvement and end-of-life replacement programs for relevant components of transmission lines.

Key words： transmission lines the phenomenon of aging fault prediction condition based maintenance
