4.5kva diesel generator frequency problem
4.5kva diesel generator frequency problem
(OP)
Hi, I have a 4.5kva diesel generator that powers my home in Spain, generally without any problems.
However, if I run the washing mashine I have to load the generator by switching on other electrical items such as a 2kw electric heater, otherwise the washing machine either fails to switch on, or won't spin, or just sits looking sulky at me.
I've been told that it could be because the generator isn't producing exactly 50hz, but all other electrical devices work ok - fridge, tv, computers, dvd, etc.
Anyone come across this problem before?
Cheers.

Do you have 1-200watts of other loads on when you go to run the washer?

Modern washing machines often use microprocessors and fairly sophisticated motor control techniques. There may be some unhappy circumstances that cannot be resolved without placing a steadying load on the generator. Extreme sudden swings of power factor may a problem too.
The speed/voltage regulator in your generator may not be entirely blameless either.
Perhaps the easiest way to solve all this grief would be to hook up a 2Kw radiator bar permanently to the washing machine. Not a very elegant solution unfortunately, but one that should work.

Some types of non linear load are just not generator friendly at all.
