Re: [Amel Yacht Owners] Climma AC Capacitors

About Climma capacitors , we are in Colombia with a AC  failure  . Specialist that come , explore unit and test capacitors , nothing but after extraction of  compessor oil ( 50 g in the cooling gaz circuit ) , all remain well , even if the compressor seem low in cooling capabilities , mainly due to internal loss of proof between gaz / oil .
On our Climma compact 9 , electrical specs are : 220 v + or - 10 % , and 50 Hz + or - 10 % , and capacitors labelling 50-60 Hz , so , to me , I think that electrical failing comes for most from the bad quality of power .

Hi Bill,

Remember the our boats are meant to work at 50 Hz we often plug into 60 Hz.

The motors run faster and the capacitors definitely do not like 60 Hz.

Can anybody explain how I have gone my entire life working around household, industrial and marine equipment, and never replaced a capacitor on a motor, yet it seems to be a routine failure we talk about here?  Am I just lucky?  Or is there something going on?  Now to be fair, very few of the electric motors I have used around boats have been AC motors, so it might just be a sample too small to give useful data.


Is there something special about the electrical supply characteristics or the general environment on board that is causing this?  Maybe salt air getting into the capacitor and shorting out the plates?


For what it is worth, I haven't had a failure of a capacitor on Harmonie--yet. (I am sure just that just jinxed at least one of them!)  On the other had, we hardly ever use any of our AC motors, so it might just be a usage factor.
