Hi,

Yes, we have a PARTICULARY bad supply. We have been going through APC BackUps batteries at a rate of six month per set. As said, within a normal working period I measured between 215V and 260V.

I only noticed because a spare UPS I stuck the PC's in my office on (too many blackouts during "Generator tests" the whole hospital is Victorian) I constantly heard it clicking on/off and checking the frontpanel revealed it was either boosting or bucking the mains, usually for extended periods.

Aparently the nearby industrial estate is responsible and the power companies only need to deliver a 240V average across a 48 Hours period, or so our Facilities people told me. As some of the stuff up here is considered "business critical" we had a massive online power regeneration system put in, with added battery packs to keep the floor running for a while on battery power untill the generators kick in (if indeed they do). Completely dispicable conditions!

Ciao T
