Re: [Amel Yacht Owners] Onan frequency variation

Jean Philippe is right!
Even thought I mentioned it a few months ago (1500 rpm for 50 herzt) I forgot about it!
Unless you can hear your genset going faster (which I hope not) than looks like my intuition is on the right track regarding the microwave oven leaking...

Hertz are a direct relation to the RPM of
your genset AFAIK. 
Was great meeting
yesterday pm. :-)

Hi all,
I recently installed meters
on my 230 volt panel and have been using them to monitor the
volts, amps and frequency of both shore power and the
generator.  Today, one of my crew noticed that the
generator was unexpectedly putting out at much to high a
frequency (75 Hz).  We turned off the microwave he was
using, but left the 100 amp and 30 amp chargers going.  The
frequency settled down to the normal
50Hz.
Not
understanding how a microwave could affect the frequency put
out by the generator, we did several experiments and found
that the frequency began to fluctuate under high loads, and
the microwave was not part of the issue.  Later on, high
loads had no impact on the frequency, so the problem seems
to be intermittent.  Has anyone else experienced this
issue?
