We were working at a storm well site today with engineer, electricians and us. The motors that run pumps and Gates are high voltage systems with a train car size diesel Cummins generator that also supplies 120 vac to instrumentation and SCADA systems..(converted to 24vdc)...they have a refrigerator size APC UPS for panel and radio...when generator kicks in...UPS continues to supply power for a bit then alarms with fault wire message. The electricians tested lines, added and bonded more grounds but nothing changes with either auto or manual switch. Our panel does detect issue and cuts off UPS feed, and sends message to water company operators over radio feed. After several tests and measurements, engineer suspects the Cummins generator is not grounded properly. We are going back Tuesday with Cummins tech. Never saw so many Fluke high end meters and testers in one place.

AS a side note, you should always use an online UPS when backed by a genset.
