Generator ATS Provides Power During Partial Power Loss

A Generator HTS/ATS Can Provide Power When One Leg Of Power Is Lost
[ad#block]Question: I am in a building in Summit county where there are no known power outages. I am assuming there is three phase coming in to our building by the looks of the transformer outside. We have a backup generator which is a Generac Elite series that is supposed to supply backup power for half of the building. Earlier today the power went out in 1/3 of the building.
- I am assuming just one phase went out, and so the generator kicked on and has been supplying power ever since. Now the reason I am thinking just one phase went out is because we have two HTS transfer switches.
- One has standby operation lit with utility power not lit, and the other has utility power lit and the switch position is utility. Is it possible that there is a problem with the power company that just one of the phases are down? And if so, should I report this as a power outrage?

Thanks for your electrical question Eric.
How a Automatic Generator Transfer Switch Works
- Eric, I don’t believe this is a problem with the utility company because the power failure has affected only one third of the building.
- I would check the main circuits upstream from the functioning HTS/ATS where you may find that you have a tripped breaker or lost one leg of the three phase power, therefore the ATS is doing it’s job by automatically providing generator power due to a electrical circuit failure.
