How engineer will come to know whether line conductor is good to use or need to replace it

How engineer will come to know whether a transmission line conductor is good to use or needs to be replaced? Well, there are a number of tools that can be used to find out. Visual inspection: This is the simplest and most common way to inspect transmission line conductors. Trained inspectors can look for signs of damage, such as corrosion, cracks, and cuts. Infrared thermography: This tool uses infrared cameras to detect heat signatures. Hot spots on a conductor can be a sign of corrosion, loose connections, or other problems. Ultrasonic testing: This tool uses ultrasonic waves to detect defects in the conductor, such as cracks and gaps. Electrical resistance testing: This tool measures the electrical resistance of the conductor. An increase in resistance can be a sign of corrosion or other damage. Line sag measurement: This tool measures the amount of sag in the conductor. Excessive sag can be a sign of conductor damage or deterioration. Well, these are some ways to figure it out.
