| Abstract: | Angle method is one of means to observe the sag of overhead transmission line using theodolite.For the large span and sag as well as large altitude difference of overhead transmission line hanger location,it’s convenient to applying the angle method to observing the sag,thus meets the requirement of accuracy.The paper introduces sag observation accurate calculation and application using internal and external span angle method,and proposes some questions should be concerned in construction. |
