Occasionally I get emails from my NUT system saying that one of my UPSes lost power for about a minute.
Date: 15. nov 2010 17.40.25 CET
Date: 15. nov 2010 17.41.34 CET
69 seconds later. But why? None of the 3 other UPSes reports any power loss. What is the problem?
So I made some scripts that logs the input, output and frequency at the time of power loss, but they show nothing strange. Today results was:
input 228.9 V
output 228.9 V
Today the UPS was a APC Smart-UPS 3000 RM, but I have seen it with other UPSes as well.
How normal is my experiences?
