Hi Thanks for your answer. It's all a bit complex for me, plus I'm not an electronics engineer, and especially not an electrician. I would have liked to have results like this photos taken when someone was testing their own generator. (photos for information purposes only) Some people say that...

Hi everyone! :)! I would like to know if anyone has done any testing on the % of THD and the Sine Wave test on that Westinghouse WGEN12000DF Generator? I would really like to confirm that this generator produces exactly what it claims. Westinghouse does not want to provide me with the Benchmark...

There no mechanical governor on this generator. So there a stepper motor is operated by a control board assembly (the 549407 part shown) which would be sensing the generator output frequency and adjusting the stepper motor as needed. (see below) Here the picture of the Generator multimeter.

Yes and they told me that generator works within their standards.

Thank's i apreciate your answer. I check my operator manual but i found nothing about the % of Hz (see the attach files)

Because this monster weighs 375Lbs and the nearest repair center is 30 miles from my house. In addition I have to pay for the return transport. $350. If I can do something myself for fine tuning that would be great.

60.00Hz right on the line

Hi I'm new in that Forum! And it’s my fist Forum to… OK I bought a Westinghouse WGEN12000DF generator and I notice that when I run it it puts out 243V and 63.2Hz! But after I put 3000W on my generator with 2X 1500W heater the voltage indicated 120V but the frequency Hz indicated only 63.3Hz (see...
