This component models a saturable reactor. It can be used in either single-phase or single-line, 3-phase circuits.
Data can be entered as a table of pairs in the form of Irms-Vrms , i-l or H-B to a maximum of 10 points of data. If more data points are available, then an external file can be used with a maximum limit of 100 data points. Successive data points should increase in magnitude. If successive data points do not correspond to a continuously decreasing rate of change, offending data points will be removed and the user will be informed through a warning message.
The following conversion formulae are used to compute the corresponding actual values, based on the input base and per-unit parameter data:
