UPS reporting problems with Phase Difference and Frequency

Johno12345
I have been asked to investigate a repeated occurrence in the UPS event log which is:


On battery power in response to frequency and phase difference


I have said that there isn't enough info to go by, but wondered if anyone had any pointers about what it might be? 


The only noteworthy thing that has happened here is that I have had the PFC repaired, so our PF has gone from .9 - .95 to unity.


its a large industrial site, biggest motor is 120kW

    thanks for that, helps it make sense to me. 


    With the size of the place, its full of machinery that could cause a voltage sag, and I know in the past we have seen the effects of supplies being switched around on the HV network. 


    As expected, nothing further has come from the IT department regarding the issue, so ill wait and see!


    Thanks
