He is a Swell Wink, even if his Glitches give me Saggy Bumps

Swells, Winks, Glitches, Sags, Bumps.. are terms to describe electricity... but did you know that the engineers at IEEE actually have engineered official terminology for power problems.  There are five problems:

1. Transients
2. Interruptions
3. Sags
4. Swells
5. Waveform distortions

Mercifully, a smart battery backup unit can address all five.  APC's interesting white paper covers these power problems and some solutions.

Looks like APC is quietly pushing those Environmental Probes as a solution to #1 .... I personally would recommend a good surge suppressor instead of adjusting the humidity in the room.
