Electrical Equipment (Automatic Transfer Switch)

[Danielle Agamon]

What are the scenarios for the ATS (Automatic Transfer Switch to operate?)

 

[Asymptotic]

Depends on what one is doing with it. A typical application of an ATS to start up an emergency generator, and switch load onto it once voltage has stabilized in the event of a power outage.

If you have an emergency generator, such as @Asymptotic mentioned, it is forbidden to have your house connected to the power grid and the generator at the same time. The ATS is used to switch your house loads from the grid to the generator, or the generator to the grid.

Somehow, to me this seems like a question off of a test.

Agreed. @Danielle Agamon -- what is the context of your question?

The scenarios to operate ATS are
1.Switching of the ATS when the UPS goes to or from "on battery" mode
2.Dropping the load when the ATS switches sources while both appear to have power
3.Revise the voltage transfer range from medium to wide, revise frequency deviation from +/-2 Hz to +/-3 Hz on the ATS
4. Set the source preference from source A to none on the ATS
