from the UPS (communication layer), you really have power failure / restored.
Search for UPS.PowerSummary.PresentStatus.ACPresent
the value 1 means "Online", and 0 for "On battery"

Does the problem occur frequently? The more details, the better.

from there, 3 possibilities (need more details to audit):
- if the problem occurred only once, then you've seen a battery test,
- else you have some electrical problems upstream,
- else the UPS has some internal problem.

A workaround would be to increase upsd.conf -> MAXAGE (ie to 20 - 25)
and upsmon.conf -> DEADTIME (to 20 - 25 too)
