Conductor (bundle) | Number of conductor defined by the number of phase plus the number or ground wires. | |||||
Phase Number | Specify the phase number to which the conductor belongs. Several conductors may have the same phase number. All conductors having the same phase number are lumped together and will be considered as a single equivalent conductor in the R L C matrices. For example, if you want to compute the line parameters of a three-phase line equivalent to a double-circuit line, you specify phase numbers 1, 2, 3 for conductors p1, p2, p3 (circuit 1) and phase numbers 3, 2, 1 for conductors p4, p5, p6 (circuit 2), respectively. If you prefer to simulate this line as two individual circuits and have access to the six-phase conductors, you would rather specify phase numbers 1, 2, 3, 6, 5, 4 respectively for conductors p1, p2, p3, p4, p5, and p6. | |||||

X (meters) | Specify the horizontal position of the conductor in meters or feet. The location of the zero reference position is arbitrary. For a symmetrical line you normally choose X = 0 at the center of the line. | |||||
Y tower (meters) | Specify the vertical position of the conductor (at the tower) with respect to ground, in meters. | |||||
Y min (meters) | Specify the vertical position of the conductor with respect to ground at mid-span, in meters. The average height of the conductor is given by:
Where:
Instead of specifying two different values for Ytower and Ymin, you may specify the same Yaverage value. If you need to access the ground wire connections in your model, you must specify these ground wires as normal phase conductors and connect them to the ground by yourself. | |||||
Conductor type | Specify one of the conductor or bundle type numbers listed in the first column of the table of conductor characteristics. See section Conductor & bundle characteristics |
