    1MW Generator Field Collapse on Load Transfer

    Haven't had the chance to test again since the field collapse, edison123. waross, I forgot to ask but what would you propose as a solution if I can indeed find the capacitor inrush from the UPS to be the problem? Retrofit a new AVG? Ronald Houdy, Jr. "We can't help everyone, but everyone can...

    1MW Generator Field Collapse on Load Transfer

    Interesting. I did not even think to check that. Do you think that there is still a possibility if that checks out that the AVG could be found to be defective if a reactive LBT is performed? I'm also wondering if it is worth performing a test on the excitation to make sure there are no faults...

    1MW Generator Field Collapse on Load Transfer

    Thanks for the reply edison123. Perhaps? It is a bit odd that this has not been an issue before now if that is the case, though. How would you suggest testing for that? Ronald Houdy, Jr. "We can't help everyone, but everyone can help someone." - Ronald Reagan

    1MW Generator Field Collapse on Load Transfer

    Thanks for the input waross. I definitely have a feeling it's from the sudden current draw on the system. I did not think about supplementing the AVG with a power supply. I am somewhat concerned though that the AVG may be defective as I realized we did not do a reactive load bank test on the...

    1MW Generator Field Collapse on Load Transfer

    Yesterday we had a power outage and our emergency diesel generator had to take over for a while. It had a mechanical failure a few hours in and we had to repair it. The generator in question is a bit older, about 25 year old, and is rated for 1MW. It supplies power to some computer HVAC...
