They explained that a ground fault prevented generators from delivering power. Manual start doesn't help in that case.

- rdl 15y agoFrom what I read, they said ground fault confused their PLCs (synchro gear for paralleling multiple generators). This shouldn't affect the generator (engine, generator) outputting power. Electronics are much more sensitive to ground faults, etc. than mechanical and electrical devices. A big manual transfer switch (as backup), which is presumably what they ended up using, is fairly bulletproof.
