[time-nuts] No more 60Hz! TEC Elimination

[Will Matney]

We have AEP here, but it's like you said, go out in the country where
Buckeye Rual Elect. is, and you have outages all the time, and you don't
want to live there in the winter.

Clocks is not what I'm concerned over as much as certain pieces of
industrial equipment that must rotate at a certain speed, or are supposed
to. Also, if they are going to allow the frequency to get slower, any
motor, or transformer, needs more iron in it, and just a 10 Hz difference
is enough to amount to a significant increase in iron. One can easily use a
50 Hz transformer on 60 Hz, but not a 60 Hz on 50 Hz. The speed difference
in motors from 50 Hz to 60 Hz would be around 1.2%, just roughly guessing
it in my head, at 1800 RPM, and we don't know how much they intend to allow
it to vary.

Best,

Will
