Thank you for the link to the PDF of generator specs, that’s ideal. As I thought, all the generators described there are asynchronous variable speed with power frequency conversion to match the line 60hz.
Fascinating reading... I’m an electrical engineer (among other things) so I’ve got lots to enjoy in that document. Thanks again!
And when i was in the air force I was a power production specialist, that is a diesel mechanic and an electrician. Power plant operator.
