Dear Professor Zimmerman,
Thank you for your time.
Please confirm if my understanding is correct.
For this duplicate branch

77 80 0.0294 0.105 0.0228 0 0 0 0 0 1 -360 360;
1/r_t =1/ 0.017 +1/ 0.0294 ---> r_t=0.0108 *OR* r_t = (0.017 + 0.0294)/2
In general, the line ratings RATE_A, etc, would also equal the sum of the
individual line ratings, but in this case the capacity limit is not given
(interpreted as unlimited) so no change.
However, a quick correction … while the total impedance (r and x) are halved,
the total line charging (b)
