Re: [Emc-users] Seeking ideas how to sync an AC generator to 60 HZ average.

[Jack Coats]

At one time I heard there were legal reasons that caused the 'grid' to keep
frequency long
term stable.  This is why AC clocks are basically 'never off', the frequency
does vary, but
within 24 hours they still must have generated the same number of 'cycles'.
 This allows
them to 'slow' the cycles or 'speed up' a bit, but still counting cycles
over a long period is
what makes it appears so frequency stable. ... just my thoughts.
