- Just in case you didn't notice,I really love quack products. I've taken apart similar units to this in a plug-in version, but this is a stand-alone aluminium case version.
OK, it's smaller than I was expecting, but that's just one of those things. It uses pretty much the same circuitry, basically a capacitor in parallel with the mains, but has a more sensible LED drive circuit and a fuse too.
These things claim to lower your electricity bill by filtering/improving the mains sinewave. They're loosely based on power factor correction, but as that has no effect on a home electricity meter they won't show an effect. They are also just a random capacitor value permanently applied across the mains, whereas proper power factor correction should be matched to a specific load.
This version is quite stylish.
This video also shows how accurate the capacitive reactance formula is.

The best electricity saving device I've seen was a really long extension lead plugged into my neighbors garden shed ..... going to my house.
+Slot1Gamer you need it for all those consoles
or from the streetlights to your house (only works at night) but its genuinely one ive heard of people doing lol
+The Mad Hammer I can imagine those with EVs would top up in large parking lots this way.
+The Mad Hammer - Here in the UK street lights are always powered on, and switched with a photocell at the top of the lamp.
good girl！he use the tool all made in china，haha😄
Big Clive - these things REALLY work! I've plugged these into EVERY single power outlet in my house so now I can't plug anything else in and my power usage has dropped dramatically! Thinking about it, I probably would get a better result just shutting off the mains circuit breaker to the house...
Brilliant!! Let me try it too... he-he
These "magic" boxes should also come with pamphlet instruction to disconnect or turn off all unused appliances, including power supply bricks, which will probably save more than that measly 0.496Amps. lol

I knew it was of Irish origin, but since you mention French it makes more sense, as I'm a Cajun. :P
ratcat17 Lol, I live in the U.S. Cajuns are basically just exiles from France and then Canada. :P
Top tip if you think a case may be live: Don't touch it with the inside of your finger tips, the muscular contraction can cause you to involuntarily grab the device (which isn't good). Use the backs of your fingers instead. That way, any muscular contraction pulls you away from it. Even topper tip: Use the right tool for the job :D
+Zadster Even better tip... get someone else to grab it!!! Or be sensible and just don't touch it! lol Great tip though... same as the electricians with one hand always in the pocket ;)
Chris Landry Indeed... they are quite elastic in nature and bounce back from nearly anything! :-O
Just give it the foreskin test. You get a hard on and touch the case with the very tip of your foreskin. If it retracts, it's live.
Zadster
I always get the cat or the dog to go sniff the appliance in question. If the appliance throws a shock they alert me immediately.
With AC there will be no muscular contraction. Still best to flick with knuckles to test for live as the contact is relativity high impedance and all you get will be a tingle.

You got the deluxe model with a fuse!!

A 200kw fuse apparently.
But the fuse is fake~
😂
Clive, have you ever thought of doing a video showing all your bench equipment? Like one video that shows all your bench power supplies, all your multimeters/capacitance reader/etc, power monitors (AC Eco Eye, your various USB 5v dongles, etc), and whatever else you generally use during your videos but which we might not see, or not see for very long.
Some of them show up briefly in the videos when you use them, but for example I've never seen which bench power supply you use (maybe it's in an earlier video I've not yet seen.)
So I thought it would be useful to have one single video that showed it all in one go, with reasons why you chose those units and suggestions for newbies on what to get and what to look for.
Like you did for electrical components and then soldering stations, but for "bench equipment" or "measuring equipment" or whatever the best name is. Cheers!
Thank jesus. My sinwaves were getting very rough
Well 5g may cause a allergy season reaction that never ends creating nasal sinwaves effected by the moons industrious gravity.
My "sinus"es were getting congested till I got this. he-he
This is a very nice case that definitely would cost more if you bought it from a major distributor as new (not new surplus). And then the power input connector and the fuse holder - that’s quite a bit of value. I might order a couple as project boxes. People selling may be confused how Clive’s debunk video garnered them sales, lol. (Of course they probably don’t care).
My compliments, sir, and admiration too ! Through 50 years as an engineer and home tinkerer, it never occurred to me to replace an AC dropping resistor with a series XC. And what a nice enclosure in which to deliver garbage !
Bang good products.
When plugged in it Bang's good.
😂
I've often had this exact same thought. You contact them to report defective products and they can just say, "well what's the problem? You did buy it from bang good" lol! The moral of the story, Only report products that don't bang good ;)

i thank you for taking the time to show us these quack devices, realy appreciated!
In factories or other industrial installations, the facility engineer knows about inductive loading; the correct capacitance for every device is wired in with the device. In fact, if their vendors are on the ball, the correct matching capacitor will generally be part of the device (at the very least, the documentation of the device will advise the capacitance needed). It’s not like this is something that was just discovered - Steinmetz wrote about it while he was creating the fundamental principles of electrical engineering.
You give most facility managers far too much credit for understanding the electrical systems in their installations and factories …
@@andyxox4168 Of cause facility managers understand the site electrical systems, if the facilities electrical load is significantly out of phase (inductive or capacitive) the Utility will significantly increase your Unit charge. Be aware, even if you alter your inductive or capacitive load your meter will track the modified Wattage consumption and you will also be down on power.

"it's a naughty, charlatan's device but it's quite cute nonetheless"
gotta like the video just for this phrase
If you have an inductive load... oh there is a circuit board in there
If you have an inductive load... there is the capacitor
If you have an inductive load... oh hold on
I literally scrolled by as he said that.
Aperture Laboratories same
If you have an inductive load it buggers up the phase of the power. Pulls the current in one direction relative to the voltage. A capacitor pulls it in the other direction. So it cancels out.
As a capacitor charges, it pulls large current even when the voltage is low, when the voltage is starting to rise in it's sine wave. An inductor resists change in current, so only starts to draw current a while after the voltage rises.
Electric companies don't like large inductive loads, because their system, and most loads, is based around the idea of loads being resistive, with a 1:1 relationship between voltage and current. Disturbing this messes up the system. So if you're a factory with huge motors, the electric company charge you extra for that.
But it only makes an actual difference if you have large loads. A little motor won't make any noticable difference. Nothing domestic should be any big deal. And electric companies only charge you based on a resistive model anyway.
So a capacitor in a box won't make a difference. And especially the tiny one here. You need proper big capacitors to balance out proper big motors.
And that's how Clive's sentence would have ended.
Diplomatic. He plays a safe game. But on the other hand he also talks about how good this portion, and how that portion is not enough to do the trick. Which means Clive knows exactly what is needed to save power. But, the diplomacy and safe game again.
But well, greenaum explained us a lot.
Question: if I have old fashioned power meter, with inductances within, instead a new digital power meter, would it make a difference? Nobody mentioned such thing, it would be interesting to do measurements. With inductive load, of course. Can you do that, please?
Your videos are always so chill and comfy

I had to LIKE this video. After 20 years I FINALLY know how to use the Memory Function of a calculator.
A small cap across the mains in not going to do much if anything to clean harmonic distortion and noise from the mains, and cleaning the mains supply will not make any noticeable difference to saving on you're power bill either. Big Clive is 100% correct excellent video. The cap across mains is typically intended as power factor correction and needs to be matched to counteract a inductive load such as a motor transformer or inductive lightning ballast. The bogus 200kw rating, the lies about saving power, and failure to provide a protective earth, is concerning. No earth on exposed conductive parts is also a breech of the regulations in most countries.
'having a bang good evening'
that joke is like 'installed linux had a bash'
Excellent result with the correct capacitor meter and the measurement values and the result is spot on. Nice case and at least no loose items in the box. The 200kW may relate to the power savings over a year, in a lightly loaded house.
The salesmen used to have demo cases with a very lossy unloaded motor to show the apparent power savings.
It is essentially a PFC device (Power Factor Correction). They are used to correct for inductive loads on the power line, to bring the current draw into phase with the voltage draw. Using LED bulbs will do the same thing as that device, as they place a capacitive load on the line. In the house, it will be mainly anything with a motor that places an inductive load on the line.
Err. Exactly what our man said.

Hello, just wanted to say I enjoy your videos. Thank you!
Cheers again Mr Big, Delightfully explained .
All domestic power meters measure the voltage and current independently and then combine the result in a power-consumed reading in kWh. Nothing else happens in the meter. Altering or fiddling with power factor will do nothing. There are NO magic devices that will change your power reading legally or any other way. If you don't like your power bill, either use less of it or get your own generator.
I did once toy with the idea of coming of grid and buying a 100% duty cycle gas powered generator. Given the fact I am paying 8.6p per kwh for electricity and 2.9p per kwh of mains gas. I know that they're nowhere near 100% efficient but if I could also get rid of 23p per day stand charge for the electricity meter I might get close to breaking even. Until the generator requires maintenance or repair of course.
There's piles of people who have thought the same as you. Best way to go is get on the websites/forums where they talk about that stuff and get all the good info from them. Meet them if you can and have a look at their 'installations' and see what might fit for your location. If outgoings (dollars or pounds or whatever you have) is the issue, a cheaper way to live is just to look at your outgoings and look for savings there. You might save 5 times what you'd save on going off-grid if you halt wasted expenditure (?).
Right, gaming the meter isn't the point of power factor correction. The point when it is legit is to use less power by correcting for the actual load used. Of course that is going to have to be an active device, not a passive one like in the video.
For example, a power-factor-corrected supply for a table saw would generally be expected to save power. It might work for the blender, too. Large appliances that actually use a lot of power already have their own PFC though. But if you use a lot of old or cheap power tools, there might be room for PFC-based savings in the shop.
For older meters it works. This device is for China market they still use the old meters.
Exactly. Adding a capacitor to a highly inductive load will improve the power factor, and the measured current will be less, but the actual watts remain the same. The meter measures watts (KW), not KVA. Take this example, I've used values that are simply to multiply: A motor is running on 200volt, 10 amps at power factor 0.7. Multiplying volts by amps gives 2KVA. The actual power is 1.4KW (multiply KVA by power factor to get KW). If you add enough capacitance to get the power factor to 1, then the power will still equal 1.4KW. The current will actually drop to 0.7A. Showing people the current dropping to 7 amps is very convincing, this is how they get fooled by these devices.
"ELI the ICE man"
ELI = with L (Inductance) Voltage (E) leads current (I)
ICE =with C (Capacitance) Current (I) leads voltage (E)
Capacitive reactance negates inductive reactance to improve power factor and reduce reactive current.
+RIB B
Do you really need a mnemonic for that? It't obvious that you need to put some charge (=current x time) into a capacitor before the voltage rises.
+superdau But not everyone is a fucking expert like you fella.
How about trying to encourage people to learn, which is what this channel is about, rather than belittling their efforts.

Sin wave drawing skill level 10! A master at work here boys :D
I'm an electrical engineer and I love your channel.
I had an excess solar panel 250w and just for the heck of it i got a small 300w Chinese grid tie inverter to see if i would save some electricity (more of a environmental than financial curiosity). I had it since last august. About two months ago i got a legal notice to have my power box examined as it appeared that i was "abusing" the meter. the measurements showed too little consumption for a long period of time. I don't have much power consumption to begin with as i have a hybrid solar and gas heater and gas stove but didn't expect that outcome...
wow looks like the spare 250w panel started saving you energy to buy from grid, power companies dont like that..im assuming the inverter is a pure sine type, anything else would trip the elcb
+fidel catsro They sure don't. I certainly didn't expect to be dragged from office to office explaining myself and my measly solar setup, not to mention the threats of legal implications. The inverter was indeed labeled as pure sine though at that price i wouldn't be certain of anything.
would love to know more about your set up. do you have a utube video about it?
Hello how can I get a set-up like yours?
Your power inverter must SYNCHRONIZE the waveform with the incoming power, or there will be trouble.

Do all you people want Google to remove the comment section? Please be respectful and kind to a person sharing information.And usernames say a lot about your character which I'm sure that's the point your trying to portray. It's not impressive and very small of you
I admire your critical thinking and research for the truth. I hope it's contagious.
Power factor isn't just about meters. The reason you want a power factor close to 1 is because if the current is significantly out of phase with the voltage, you actually need to pull more current over the wires to get the same power (so a 100W device with a power factor of 0.5 will result in roughly twice the current flowing over the wire than a 100W device with a power factor of 1.0 (for the same wattage)). That means you either need much beefier wires, or you can end up with a lot more heat and resistive losses in the wires. This is why it's particularly important in industrial (or datacenter) contexts, where you have lots of equipment pulling lots of power from a given circuit, and you want that to be as efficient as possible.
Capacitors can also be used to filter out higher frequency electrical noise (which is probably what they were getting at with the sine waves on the box), but that generally requires having the thing you're protecting be on the *other* side of the capacitor from the noise source (or very close by). Just plugging a capacitor into a nearby socket will do nothing in that regard.
Not only do you get to play with "a naughty little charlatan device", you also get $5 worth of parts to make a new project...
The cap would make a good bypass cap on a pro audio driver
Would have been nice to see the actual sine wave before and after with an oscilloscope and possibly a 24hour test running once without the device and once with the device to see if it actually lowers the power consumption on your power meter that the utilities read from. Other than that - very detailed explanation! 😊 thank you.
Residential power meters measure both the power going into your home, as well as the power reflected back to the power company, with the net being what you actually consume.
Power reflection happens from inductive loads which temporarily store power in a magnetic field then when that field collapses, it send that power back to the utility. While that can add current in your power lines, your not actually consuming it and so aren't charged for it. Capacitors also store power in the form of a electrostatic potential between two plates and releases it back to the grid. Each unit of capactive reactance cancels the same amount inductive reactance.
So while you seen .489 amps at 240 volts you were not seeing 117.360 watts being used. Rather, you were seeing 117.360 volt amps being absorbed from and reflected back to the mains line.
So these devices actually increase* your charged-for consumption, in a residential situation?
*by more than the power consumed by the LED, obviously
Ian Oliver "
So these devices actually increase* your charged-for consumption," Simple answer: No. More complex answer: Maybe just a tinny amount. Read below for a more detailed explanation.
Look at this image of a capacitor in an alternating current circuit. sub.allaboutcircuits.com/images/quiz/00577x02.png
Power is Voltage times Amps. Consider these four different situations with a capacitor during a complete (0-360 degrees) cycle of applied alternating voltages.
1. 0-90 degrees of a cycle, voltage and amps are both positive. so power is positive and you'r consuming power.
2. 90-180 degrees of the cycle, voltage is positive and amps are negative. so power is negative and you'r sending power back.
3. 180-270 degrees of the cycle, voltage and amps are both negative. So power is positive, and you'r consuming power.
4. 270-360 degrees of a cycle, voltage is negative and amps are positive. So power is negative and you'r sending power back.
Adding up all the power flows. gives you a zero net flow of power. A little more nuanced answer: But, if you add in the tiny amount of resistance found in the wires, then yes you will loose a tiny amount of power due to line losses. For residential consumers, it is generally so insignificant that its not worth mentioning.
"Your charged for consumption" is the net power that you consume. These devices temporarily absorb power and reflect it back. If I gave you an apple and moments later you give it back, you didn't actually consume it, thus I cant charge you for what you did not consume. But, the apple still changed hands twice. The apple in this analogy represents power not current. This is how it is with residential power consumers.
Industrial power consumers are a special situation. They consume so much more power and often have very poor power factor.
If we carry on the analogy, were you I might have exchanged an apple, Industrial consumes exchange truck loads. If power lines are like freeways. those freeways can only allow so much traffic, unnecessarily exchanging truckloads limits the number of truck a given highway can deliver. Adding an extra lane helps, but is costly. Alternately, power companies charge industrial consumers for the actual power flow rather then net power flow. This creates an incentive for industrial consumers with poor power factor (often excessively inductive) to employ power factor correction through introducing capacitive reactance.
Florian Uhlemann you do recognize, that this device is not powerful enough to do anything except blank that stupid old green LED. The point he was making was in the event that you had a device that function correctly, through it, One could change the differential between phase of voltage and amperage. I don't care if you put a big Flippin magnet on this thing it won't do anything at all to your bill. But know this is a Chinese POS, with false advertising, and dreams of grandeur, straight up and out right bullshit, nada,nit,crapola!!!! In the American vernacular Dogshit tastes better than this works.....LOL

I fully agree with your recommendation that if one desires to save on electricity, setting the AC temperature one degree higher will result in significant power saving. Or placing the cooling tower would significantly reduce the energy consumption. A sucker is born every day for these gizmos!
This guy is amazing!
What's amazing is how people who "know" electricity can never explain it to those who don't. :)
6uf 450v caps are used for window type air conditioners in the Frigidaire brand. They have a mounting tab that appears to be broken off on your cap in the video.
An oldie but a goodie.
I've only ready about a hundred of the comments but I noticed a few talking about switched mode power supplies (hereafter "switchers). My tuppence worth:
In many modern settings, domestic and office, the biggest contributor to poor power factor is the multitude of switchers in electronic equipment. Unless they are designed with "active power factor correction," called "active harmonic filtering" (or something similar) in some places, switchers have awful power factor but it is not simply a matter of phase difference between current and voltage. They are non-linear loads (and have a negative input resistance characteristic to boot, but that isn't really problematic).
When you directly rectify and capacitively filter AC, current only flows when the instantaneous DC voltage out of the rectifier exceeds the instantaneous cap voltage. This means that the current only flows near the peak of the AC sine wave and the peak current can be VERY high - the higher the filter capacitance the higher and narrower the peak current "spike" (meaning the RMS to average ratio is higher). In practical terms you cannot fix this very non-linear behavior with simple linear parts like capacitors (some "valley fill" techniques can be used to improve power factor, but the the parts cannot just be added external to the switcher). Active power factor correction is typically done with a boost switcher that makes the instantaneous input current directly (first-order) proportional to the instantaneous line voltage - but, in a feat of magic, INVERSELY proportional to the input voltage averaged over several cycles (that's the negative input resistance coming into play). The result is input current that is sinusoidal and nicely in phase with the input voltage. Typically the DC bus voltage would be around 385V for "universal" input (85 to 265 VAC).
Great video. Appreciate it was done years ago. I believe no appliance is permitted to have a thumb - screw type fuse holder as you must use a screwdriver to access the fuse.

Thanks for the great videos. As a side note, it would be worth buying just for the case
tx for the info.
I was really curious about this. I never believed that those gizmos do anything. Very good explanation about how people believe that the thing works,
It happened that I fooled myself too in such a manner. two years ago, I replaced the bulb I use more with a LED one. did not noticed any saving. I use light quite little. About half a year ago I changed all the other bulbs, just because I like the idea of LED illumination. I noticed a sudden lower bill of about 30 percent. I was convinced that the new bulbs were the cause, even I use them just few minutes daily. I simply denied my brain to do the math. The first one I changed I use it about 2 hours daily. Recently, I woke up from my dream. I realized that I should had have about 30 hours daily of bulb usage to perform that saving.
I do not really know the cause but I guess it was a short on a socket. It exploded about the same time, so I replaced the wiring. So, before the short, just had a trickle of about 120 w. Maybe I am wrong, but this is the only idea I have to solve the mystery
Most household appliances are quite inductive. This results in inductive current (VAr:s) flowing in the wiring alongside the work current (Watts). Although the VA current does no work it will generate losses in the wiring.
This device is just a capacitive compensator. Technically it will reduce the total VA current resulting in less losses in the wiring.
There are some safety aspects though. If an appliance VA current is completely compensated there will be resonance. This could result in strong currents between the appliance and this device. There is a fire hazard. If an appliance is to be compensated the appliance should always be fitted with its own capacitor inside the appliance casing. Appliances should never be fully compensated. The efficiency factor (cosine fai) should not be more than 0.95. Resonance currents may explain fuse box or switch gear explosions.
The grid voltage usually contains strong harmonics. The third harmonic is the strongest. They are usually caused by driving the grid transformers close to saturation. These harmonics are actually cleaned up these devices, to some degree, but they can cause the capacitor to run quite warm. The capacitor will deteriorate fast and eventually short out. They may explode.
Lighning causes shock waves in lines and house wirings. The shock wave will go where the impedance is smallest. A device like this could provide that. The device may explode. However. It may save other appliances from destruction.
Isnt the reason we drive ground rods into the ground to reduce objectionable current like nearby lightning strikes?
Do you mean that I can't just reduce my energy consumption by plugging something in, that I actually have to make an effort, how dare you lol
I followed you completely. Keep going brother. Great videos.
Worth its money for the case and bits. Nice.
U should teach, u're way better at explaining than my teachers.
Nice little projects btw
So basically it does nothing, aside from reducing your liquidity.
+SutekhAeon Maybe you're right. 99.9% of humans who change science din't get rich but poor with their interests and often loose their lives. The best way to avoid reduce your liquidity is to save every penny and avoid girls.
+dharmabodhy LOOSE? I don't think so.
How does this look? LOSE
+dharmabodhy But Where's the fun in that?
By connecting another device to the home electrical network you will only increase consumption, if you really want to reduce consumption then replace the appliances with higher consumption by others with lower consumption and greater efficiency( The savings will be seen in the medium or long term), keep off the appliances that you do not need to have on or those that you are not using. Note: It would be a very good idea to check your home's electrical network to make sure there are no leaks or loose wires.
by your calculation a little bit technician can make it own.at home
thank you sir. very informative.
How many multimeters do you have? You bust out a different one in every video I've seen.
I'm a keen audiophile and there are hundreds of quack products that apparently improve the sound. Interestingly, the more they cost, the more kudos that is attached to them.
+Mysterious Squirrel If you are a keen audiophile then you understand that such a product could actually improve sound in certain scenarios. Suppose for example you have equipment putting high frequency ripple on the AC mains, then an LC in series with an unregulated linear amp PSU, particularly on a discrete amp design with low PSRR, could improve sound. Could you actually HEAR the difference? Maybe not, an unregulated PSU powering a discrete amp circuit tends to have all kinds of unique distortions going on.
Stinky Cheese I know in the 80s a company called BBE started building what they called 'sonic maximisers'. Basically they were a pre amp that sat in the tape loop, much like an effects unit does. They were dirt cheap and brought the sound to life. Mistake 1 was the name 'sonic maximiser' and mistake 2 was the cheap price. The Hi Fi press absolutely rubbished them. Meanwhile, pointless and worthless gadgets that did nothing with huge price tags attached to them were vaunted as must have tweaks.
Mysterious Squirrel they still sell them apparently
I’d buy it just for the beautiful case - perfect base for a hobby mains project
Mostly ElectronHeads will be viewing this video which probably makes the Chinese price on this a good deal. We get a nice extruded aluminum case, 4.7uF/500V Cap, Panel mount fuse holder, Power cord and connector and a PCB! All for probably 1/10th the cost of buying the components separately!
Surely, this device wouldn't meet British Electrical Safety Standards. It is a METAL CASING, and is completely devoid of an Earth Connection. I have not read any comments (below), but this device would never be allowed into my Household! Always a thumbs up to Big Clive for his informative short info notes on almost anything electrical. Greetings from Australia.
Ah, it´s torks... a moment, I need my emergency kit! :D
wow,that muti-meter got a huge display on it!!! (may be it is the biggest i've ever seen)
+郭牧楠 That's why I use it in the videos. It's got a fantastic display.
yes,I agree.
And the shape of that meter is fantastic too!
Am I hearing some subtext here?
Also the curves of that meter are so sexy!
+Gasgiant That's what she said...
Great job. I absolutely love it when you do the math. Arduino cancer has destroyed enough of EE community. Thank you.
thank you for this information it was helpful and the way you explained the math made it easier for me to understand I learned a lot thanks
I bought one of these for the aluminum case... where i bought it it was $11 and an extruded aluminum case of that size was $9.. so i basically got a decent cap to use for something else for $2
warmfreeze your logic is screwed
The fuse holder is reusable also.
I thought the same thing, anodized case for that device was cool
the housing is nice indeed
+forestbird agree, the housing is quite fancy indeed, you could use it to house maybe a power bank or something more useful
Horadic or radio
Where I work we have larger conditioners for vfds that kept failing, we had industrial-size conditioners installed to smooth out the dirty three phase incoming power and had great success.
I need one for power filtration, dirty sine wave from the fridge compressor, having that power on standby to startup the compressor, and to absorb the overflow when the compressor stops is what i am looking for. I have found the site and specific product, i never would have known about this product if it weren't for your review, thank you so much, I am currently using a dimmer switch on a Himalayan Salt Lamp to absorb the overvoltage from the disengaging compressor. Soon i will be ordering one of these to replace the lamp.
"Power companies HATE this!"
No they don't... it doesn't work.
One clever trick.
The imbalance of the load can be read on the neutral wire. I always do a load balance and believe it has reduced my power bill. This said a friend bought a 'magic box' from an unscrupulous contractor that additionally sold him 'semi-annual maintenance' on the bogus device. I was waiting for the guy after I had explained it to my friend. They had bought the device for THOUSANDS of dollars and paid an additional $1800 annually for 'maintenance'. I worked as a licensed electrical contractor in several states and have 2 degrees in Science and Engineering. Anyway the prosecutor got in on it and the vendor did go to prison. He had ripped off many people with his scam but this was only one of his ongoing enterprises. There are ways to save on your electric bill, reducing actual consumption is the best way. There are also some electrical devices that capitalize on the way the old meters operated, squirrel cage motors were one of such devices. Consult an electrician or an electrical engineer before buying crap like this unless you are like the video maker and just checking the false claims out. Worse case scenario, you burn down your house or suffer a deadly electrical shock to your body. Best case, you've been robbed.
Neutral wire current flow as an indication of imbalanced load is a DIFFERENT CONTEXT than power factor correction for reactive loads being discussed in this example.
Neutral wire current flow in the North American residential electrical supply is to and from the center electrical tap of a 240 VAC residential supply power transformer normally in the street right-of-way. The neural center tap electrical supply line forms two 120 VAC circuits at the residence, a lower 120 VAC circuit and an upper 120 VAC circuit. Current flow is between the power supply transformer's upper 240 VAC electrical tap and its center tap and its center tap and its lower 240 VAC electrical tap.
When the lower and upper 120 VAC circuits have exactly the same loads then the neural supply line would theoretically have no reason to flow current because the current return of the upper circuit exactly matches the current sourcing of the lower circuit. That means if you had exclusively one 100W light bulb on the lower 120 VAC circuit and one 100W light bulb on the upper 120 VAC circuit when only one bulb is on the neural wire would flow all the current needed for that one bulb with a corresponding measurable voltage drop on the neural supply line wire due to the wire's resistance. Simmerly if you turn off the lower 120 VAC circuit bulb and turn on the upper 120 VAC circuit bulb you'd find a voltage drop on the neutral wire. Now, if you have both bulbs on, theoretically you've cut out all current flow in the neural supply line because current return of them upper 120 VAC circuit exactly matches current sourcing of lower 120 VAC circuit.
That means you've effectively cut out half the power line voltage drop experienced by the lower and upper 120 VAC circuits when used individually because you are sinking and sourcing current at the residence. This by-passes sending and receiving current through the neural supply line wire to the street transformer and its associated power loss.
This seems like a good idea, but I'd think the neural supply line voltage drop and power loss would be almost undetectable. Most likely if you are having electrical problems your supply wires are old and deteriorated, under sized, and many possible mechanical ills that create erratic behaviors you may be inclined to notice more after you've made some change to your electrical system.
You could also have a erratic and bad neural supply line so reducing your dependance on it improves your over all electrical performance. Most likely if the neural supply line is bad the other supply lines should be replaced as well. Old residences in North America frequently only had 100 Amp supply lines and when any large appliance would start up, like the AC, the lights would dim as the large start up current creates a severe voltage drop across the old 100 Amp supply lines. The power company will typically upgrade your lines to 250 Amp for free. Just say your putting in a massive hot tub with electric heat!
As Douglas Engle said, balancing the loads has no effect on metering on a edison 120/240 center tapped single phase supply. If the conductors are undersized then sure you will lose some from overload / causing conductors to heat....but if that is the case you need to wonder why your main breaker is not popping. I would get a qualified electrician to check the conductor and main breaker size.
Power factor, that is actually a thing - especially on commercial and industrial setups. You can get charged for a poor power factor, where the grid is providing capacitance to inductive loads. Generally the utility will bill for a power factor that is worse than 0.9 (90% of unity) This is where the amps and volts are out of sync by greater than 90% .
And I agree the annual maintenance - what a scam. Possibly a capacitor bank if the owner was running a huge amount of poor power factor equipment may help the owner avoid a power factor penalty, but it would unlikely on a residential setup.
I am glad you talked some sense into your friend.
200kW in such a small package - that is truley amazing in its self.
Here is a very useful analogy: imagine your electric motor that you want to drive is a child on a swing, and your power supply is you (periodically) pushing the child on the swing. You will get the best swing for the least effort if you time the pushes correctly with the swing. This is the idea behind these devices (when designed and used appropriately) - the inductive load is the child on the swing that is slightly out of sync with the power supply; the capacitor is like a mini battery that temporarily stores energy from the power supply and then delivers it a tiny bit later so that it is perfectly timed up with the load. For this to work you need: 1) a lot of inductive load to make the small difference worth caring about and 2) perfectly matching the capacitance with the load. Domestically, you will have neither (unless you are running weird equipment for a home and got extremely lucky with the numbers).
LOVE YOU , you use your brain them test it , giving these miracle MACHINE to prove their claims , letting the facts speak for themselves.. keep it up
