I keep hearing this stuff about power problems, and while I can understand
the need for an UPS, the need for a line conditioner evades me, possibly
because I live in Denmark which judging from the stories have much cleaner
power.
Though this is getting way off topic, does anyone know where it's possible
to get comparable data on the quality of the mains power in different
countries?
If possible, collected neither by the power suppliers nor by UPS
manufacturers. :)
