Nowadays, we use equivalent span method and different span method as sag measuring methods. These measuring methods are used to get the exact sag value. However, it is difficult to measure the sag value at an arbitrary point, and it takes a long time to prepare measurement, as well as a lot of measuring equipment is needed. In addition to it can be dangerous, as the engineer needs to climb the tower. This paper shows a new measuring method to increase work efficiency in the field area.
