device to add additional load as wind increases | 16 comments (16 topical)
Re: information re: voltage regulation device to (3.00 / 0) (#1)

Switching a major load causes a mechanical shock on and current spike in the mill.  Not necessarily fatal but may be an issue.  You'd want to switch only part of the load.

There was a discussion earlier about putting motor run capacitors in series with resistive heating loads, so the rising frequency causes the current to go up as the wind picks up.  I don't recall how that worked out.  Maybe somebody who tried it can post experiences.

(Note:  RUN capacitors.  Start capacitors don't have the continuous current rating.)

zubbly tried that with large dc caps wired back to back or something like that as he could not get his hands on enough ac motor run caps to do the job if i remember correctly it worked but he stopped using it because the capacitors got very warm under load. you can Google search the board and find out for sure its all here.

just a personal rant carry on.
