The ETAP Transmission Line module calculates electrical parameters, conductor ampacity-temperature relationship, and sag/tension-temperature relationship of overhead transmission lines. Comprehensive modeling of the coupling effect between different line branches is available. The user-friendly graphical interface displays the layout of circuits and ground wires for overhead lines. It is an easy-use tool for efficiently sizing lines, building new lines, and verifying the parameters of existing lines. |
