| Abstract: | The angle measurement on overhead transmission line sags finds a wide use in northwest 750 kV transmission lines thanks to their special features - high altitude and large span. However the adversary topographic conditions, application of 6-conductors and the arrangement of the middle phase V model insulator strings largely increase the difficulty of the measurement and the intensity of the calculation. Adoption of general-angle-formula-based computer software to measure and analyze the sag of transmission line offers a new and effective method for measuring transmission line sags. |
