+C Illustrate modeling of Type-51,52 elements to model unsymmetric series
+C connection of [R] and [L] as described in the October, 1997, newsletter
+C Begin with uncoupled branches of 1 ohm resistance and just 2 phases (no
+C Type-53). The answer is obvious by inspection: the sinusoidal source
+C voltage is exactly split in half. Very low frequency and small time
+C step means that this varies very slowly --- in the 7th decimal place.

+C 4th of 15 subcases progresses from preceding 2-phase to 3-phase. Begin
+C with special Z0Z1Z2 model that assumes decoupled symmetrical component
+C impedances Zo for the zero sequence, Z1 for the positive sequence,
+C and finally Z2 for the negative sequence. Otherwise, the problem is
+C the same: 5 very small steps of uncoupled, resistive voltage dividers.
+C About current outputs, this subcases introduces selective use of col.
+C 80 punches. Note phase C output of the series R-L-C is missing, and
+C that this is supplied by the punch on the Type-53 card. Switching the
+C zero and the 1 of these two phase-C cards does not change the numbers
+C (it only changes the heading names). That was for the 3rd of 3. One
+C can change the 2nd (phase B) in comparable fashion without changing
+C numbers of the time-step loop output. This illustrates selective
+C branch current output.

+C 15th of 15. Like preceding, except coupling is added to [R] and [L]
+C matrices. Both halves of problem still should have the same answer
+C (note matrices remain symmetric), although voltage division now
+C longer will be exactly half and half.
