Nice :)

With all the possible respect for your profession, there is absolutely
no difference in the basic theory.
Also in the high frequency domain we have short and open circuits,
discharge in the dielectric (for power amplifier) and faults.
The only difference is that our circuits are physically smaller: cm
instead that Km, but the "d/lambda" is the same. 

By the way, the RTAI project

( see also http://www.scicos.org/scicosrtai.html )

RTAI is born under ENEL sponsorship

Linux RTAI is currently used for alternator synchronization
and load sharing.

If you like, we can discuss the details :)

  P.S. In Europe we work ad 50Hz, 20ms ;)
