The Manual Data Entry component provides an alternative to using Transmission Line Towers or Cable Cross-Sections to define the transmission system. Here the user may enter transmission data in one of a number of formats as described below:
Resistance (R), Inductive and Capacitive Reactance (XL & XC): Direct entry in both W and per-unit
Characteristic Impedance (Zsurge) and Travel Time
Resistance (R), Inductive Reactance (X) and Capacitive Susceptance (B): Direct entry in per-unit per length
Shunt Admittance (Y) and Series Impedance (Z) Matrices (Single Frequency): Direct entry in Siemens and W, or Siemens per meter and W per meter,
depending on the unit option selected (as read from a data file).
Shunt Admittance (Y) and Series Impedance (Z) Matrices (Multiple Frequencies): Direct entry in Siemens per meter and W per meter (as read from a data file).
