Yes, there ARE other outputs! I was responding to the "statement" made
earlier where it was "said" that there are 600 ohm inputs not outputs.
Just like my comment that power transformers have FREQUENCY and
IMPEDANCE ratings. When a short circuit occurs on a distribution
system, These MUST be factored in along with SIGNIFICANT motor loads.
For some milliseconds the motors WILL produce power OUT.
If you do not wish to burn up transformers, power lines, and generators,
they had BETTER be taken into account.
To this day, there STILL are 25 cycle transformers in use. Especially
on significantly older military installations.
