N2 - This study evaluates the accuracy of executed sags in overhead transmission electric lines, explicitly focusing on AAAC Al 59 type wire. A novel and innovative approach involves collecting data on sags in the field, converting field data into design data, and utilizing statistical methods considering both field and design data. The research determines the maximal inaccuracy of designed sags to be 18.54% with a 95% confidence level, indicating a potential deflection towards the ground by this percentage. One notable advantage of this method is its ability to test and enhance the effectiveness of measures to improve accuracy by iterative re-feeding field data into updated accuracy calculations. This iterative process allows for identifying optimal measures to achieve the highest level of accuracy. The proposed research methodology applies to any wire type, providing practical guidelines for enhancing sag accuracy and offering directions for future studies in this field.
