Howdie Gents,
Just a note of Thanks for your inputs.
Finally back from the deep dark south of NZ. The good news is the generator is know functioning correctly. The cause of the problem being the sensing voltage had a different rotation to the terminal voltage?? Not sure at this stage if...
Thanks rcwilson, you make some good points to check.
At present there are issues with the gas well and enough gas for us to run so we have not been back for two weeks.
From my investigations I think the outstanding problem is around the sensing voltage being out of phase with the terminal...
Thanks Scotty, PF controller is integral to DVR (As first post, the DVR is fully functional as I've eliminated that by running it in a working plant). It takes its feedback from a CT designated to the "B" phase of the main generator terminals. To prove the polarity of this CT we preformed the...
We have proven the regulator to be fuctioning correctly by running the DVR in a running plant.
The auxiliary circuits (from the PLC) to the DVR are functioning correctly.
The problem seems to be between the DVR and the generator:
Voltage Sensing Circuit - 3 Phase?
PMG circuit - 3 phase?
Field -...
