PowerWorld Transmission Line Parameter Calculator Introduction The PowerWorld Transmission Line Parameter Calculator is a tool designed to compute characteristic line parameters given the type of the conductor and the tower configuration of a three-phase overhead transmission line. The parameters computed are the resistance R, reactance X, susceptance B, and conductance G. These values are computed as distributed (per unit of distance), lumped or total (for a specific line distance), and in per-unit. Calculations The following controls are part of the calculations section: Parameters Calculation This section is to enter the necessary data to compute the characteristic line parameters that are shown in the Results panel. Input Data Conductor Type: This is the combo box that lists all the conductor types available in the Conductors table. To add, remove or edit a specific conductor and its characteristics, see Conductor Type section below. Tower Configuration: This combo box lists all the tower configurations available in the Tower Configurations table. To add, remove or edit a specific tower configuration, please go to the Tower Configuration section below. Line Length: This is the value of the distance of the transmission line. The units are miles when using English system, or kilometers when using the Metric (SI) system. Line Length Units: The line length units specify the measurement system to use when entering the line length. The options are English system or Metric (SI) system. The final and
