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.

The local power authority keeps the diesel generators cranked. Hope this help a little. .

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...
