If the ball does not float, the power was smote!   |

Hey puff, keep you day job cause your rhyming skills need some work. That looks pretty cool but does it keep track of how many times it touched down or do you stay home and just watch it. I know when i get a blip cause my microwave has no tolerence of power interruption what so ever. My computer will stay on and yet the clock on the microwave starts blinking.

My rhyming skills are at least as good as Johnny Cochran's was, thank you!  If it goes down, it stays down until you laboriously refloat it. So if you are gone and it is down when you return home, you know the power was out or at least glitched momentarily. What I need to know how long the power was out is a good old fashioned ac powered analog clock. |

Ok educate me. WTF is a smote then i will retract my previous critique. And yeah i dont know if they sell clocks like that anymore, and if they did no one would be able to read it unless they are over 30yrs old. That is a cool looking device and a real conversation piece.

Last week my Power Conditioner glitched out.
It is supposed to do so if voltage exceeds 135vac or drops below 95vac. It did this TWICE and than I started pulling plugs.
At the same time NOTHING else was effected.
I called the power company. They said 'some line work' was going on in an Adjacent Circuit. And there should be NO problem.
They sent a tech out who arrived about 9pm give or take. We spoke and I told him what happened.
He said they were doing some load switching and that DOES effect adjacent zones. So much for the talking head on the phone who said alls-well.
I DID leave stuff unplugged for maybe a day. For music? I used my Transistor Radio which was fine.
No Recurrance.

Hmm - makes me wonder if the height my magnetically suspended sphere varies with voltage change? |

That would really depend on how the circuitry that runs it is designed. I would note that, if you REALLY care that much, there are fancier versions of devices like the Kill-A-Watt that log the voltage... and specifically keep track of fluctuations. However, I would also note that, unless you plan to buy a very expensive power regenerator, knowing that isn't going to help you much. The "spec" says that the power you get from your power company is expected/allowed to vary outside the normal range for short periods of time. (So, if you suspect some sort of actual problem, it's worth reporting it... but normal fluctuations are... well... normal.) There are either lots of standards, or no real standard, depending on how you look at it... and your particular power company may or may not have a "contractually agreed-upon acceptable range". However, as a very broad generalization, compared to "rated line voltage" +/- 5% is considered pretty normal, and variations of as much as 10% are considered to be no big deal. One standard suggests that "equipment should tolerate operating voltage up to +/- 10% of it's rated operating voltage". (The power company supply grid standards are generally of the form of "voltage shall not remain further than 5% above or below rated voltage for more than 5% of the time".) Note that things like the sensor on your power conditioner can be designed to respond in a wide variety of different ways. For example, it could respond to excessively high or low voltage very quickly... Or it could be designed to average the voltage over several seconds - and so to respond to "major problems" but not "little glitches". And some really high-end ones may do a "time integral" - where they consider both the voltage and the time it remains above or below normal. And some can be individually configured for various types of situations. (For example, to "trip" if the power exceeds +10% for more than five minutes, or more than +5% for ten minutes, or to trip instantly if the power exceeds 140 V. ) Last week my Power Conditioner glitched out. It is supposed to do so if voltage exceeds 135vac or drops below 95vac. It did this TWICE and than I started pulling plugs. At the same time NOTHING else was effected. I called the power company. They said 'some line work' was going on in an Adjacent Circuit. And there should be NO problem. They sent a tech out who arrived about 9pm give or take. We spoke and I told him what happened.

I'll 2nd the Kill-A-Watt. I own the basic model and it's quite handy and informative. A similar device which would log to my computer would be even better.,
My power conditioner, a Panamax, responds quite quickly to over or under voltage conditoins. Even at times when nothing else in the
house even flickers. Last week was the first time it's done so in a couple years and the 2nd or 3rd time in a decade + of ownership.
IOW? I don't think I'm getting 'false positives'.

My post of course was facetious. I own two PS Premier regenerators that I connect to source components. I was a motor control engineer for many years and occasionally when trying to trouble shoot some weird inconsistencies of our equipment, we rented a power monitor / charting device to see if the line was behaving.

The ONLY problem with the PS power plant stuff is for high power amps where they simply might not have the capacity.
For lower power and digital gear they are terrific.
I have a PSAudio Soloist Outlet on a dedicated 20 amp circuit. No longer available.
