[RE-wrenches] Slow clocks

[Kristopher Schmid]

Thank you all for confirming my suspicion regarding generators and clocks
and for the advice.  While i wholeheartedly agree that a 24/7 load like a
clock in an off-grid home seems rather foolish, everyone's line between NEED
and WANT falls in a different place.  I see it as my job to educate and not
to judge, as hard as that is sometimes.  Though i don't share their views, I
still put in systems for those folks believing in "TEOTWAWKI" (the end of
the world as we know it). 
 
Thanks again,
Kris

The way I learned to set gen set rpm's about 25 years ago was with a plug in
clock with a sweep second hand, and when the clock was good we had 60Hz.

Here in American Samoa the electronic clocks always run fast, a few minutes
gained every other day due to high frequency issues (65+Hz) that plague the
Island. The local power authority keeps the diesel generators cranked. 

 

Hope this help a little.

I have an off-grid client who tells me that his clocks lose about 1 minute
per hour while he is running his backup generator.  Has anyone seen this
before?  Do clocks use the zero crossing on a 60Hz wave for keeping time and
could a frequency discrepency in the generator cause this?

My thanks to the brain trust...
