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.

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!

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.

[@HerbertTowers]

Err. Exactly what our man said.

[@bjtaudio]

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.

[@greenaum]

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.

[@KetansaCreatesArt]

[@foogod4237]

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.

Other than that - very detailed explanation! 😊 thank you.

[@kreynolds1123]

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.

[@IDoNotLikeHandlesOnYT]

So these devices actually increase* your charged-for consumption, in a residential situation? *by more than the power consumed by the LED, obviously

[@kreynolds1123]

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.

[@eugenepohjola258]

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.

tx for the info. I was really curious about this. I never believed that those gizmos do anything.

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

[@d614gakadoug9]

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).

This is a Charlton type device. Without going in to anything complicated to explain, the power meter in your home will measure the total power used not caring about phase shifting and etc. With the power cord shown and from seeing inside of it, there is no possible way 200kW can pass through it. The power cord would melt down and so would everything inside of its case. At 240 Volts this would be over 800 Amps. At 120 Volts that would be over 400 Amps. This is a lot of power to be able to run through a small box like this. The capacitor in that unit is really in parallel to the load. It will not make any difference, other than using an extra 1/2 Amp of power consumption. In North America where 60Hz is used, it will consumer a bit more than 1/2 Amp. In actual effect that gadget will use more power and not less! Over time that extra 1/2 Amp will add up to some extra cost on the power bill. Best practice is to use good quality LED lights. CFL will also save power cost, but are being phased out slowly. The average LED or CFL light uses about 1/6 to 1/8 of the power consumption of the equivalent Lunins in an incandescent lamp. There should be a power consumption savings of about 60% to 70% with the newer technology lights. Turn off the lights when not required. In cold climates like Canada if you turn down the heat by about 2 Celsius degrees you can save as much as 3% to 5% on the very cold days. You can set your heat to 20C instead of 22C. This should work with electric, or oil, or gas heating. If you are using a space heater to have some extra heat, turn it off when not required. A space heater will consume a lot of extra power. In the end, turn off lights when not needed, and if possible run your heating a few degrees colder. Use LED lights instead of incandescent lights.

The aluminum case is used/designed as a heat sink to keep the capacitor from burning out

[@kozmaz87]

Yes this is the typical thing that would have to be way bigger for switching power supply noise cancellation in huge office buildings. Usually when office buildings went all fluorescent from incadescent every CFL or fluorescent tube lighting fitting comes with a tiny switch mode power supply within and those tend to release switching noise back to the mains and since they are all in sync their noise adds up and produces big alternating current on odd resonance frequencies blowing everything including their main power line itself when it melts :D So industrial size filters had to be fitted wasting away much of the power the so-called energy efficient lightbulbs saved :)

[@warmfreeze]

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

[@thysonsacclaim]

That plug is very weird. It doesn't have any holes in the contacts. Those are required if I'm not mistaken. You may be wondering what the 2mm wide holes bored into the prongs are for. Well they do have a few purposes: 1) They are used for Lock Out Tag Out by running a zip tie or small lock through the holes 2) They act as detents into which small balls, springs or prongs grab the plug when it is inserted to prevent it easily falling out--this is the most practical reason. Plugs without holes, and I've only come across 1-2 in my entire life, tend to fall out a lot easier 3) There is probably some minuscule amount of material saving

[@worddunlap]

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.

[@douglasengle2704]

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!

[@alexjoseph9157]

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.

My bill shows line charge, production charge, fuel charge, tax - the wattage charge is almost equal to fixed charges. I changed to tankless water heater, insulated windows, added ceiling fan & down sized the heat pump after the upgrades. Next is changing the heatpump from (air to air) to (water to air) after I remove trees. The temperatures now are 2 degrees up in summer & 2 degrees down in winter.

[@minetdbrogs9386]

[@driftedbird]

It's just a capacitor it doesn't do anything other... I could give you the technical terminology but the long and short of it is that would only work if you were paying a service charge witch is how the power company charges commercial buildings for their power bill and even in that application it's too small to have any significant effect

[@PATTHECATMCD]

I can't speak for the video maker but here in the UK it is standard practice to have a service charge "per hour" for connection to the grid. For domestic consumers as well as industrial consumers. There's an awful lot of individual suppliers. BUT it's only really going to do something if you have huge power consumption. I agree with you.

[@wybird666]

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).

[@jamescree6331]

+Gasgiant That's what she said...

[@spayderninja]

Putting that capacitance across your AC mains 24/7 is going to cause additional current draw and a higher utility bill. I bought a device many years ago that claimed to save power on my refrigerator. It resulted in slowing the motor, but that means that the motor must run longer to pump the same amount of coolant, so no power was really saved. The instantaneous power was reduced but it ran longer.

[@NafrytiNosferatu]

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.

But, I suppose if bigclive doesn't need it often then a $15 calculator would be just an extravagant expense (and with a scientific calculator he wouldn't know how to use the memory keys on a basic one 😂) even though it can be a little tedious to use.

You started to mention the phase relationship in an inductive circuit and a capacitive cicuit... we had a way to help remember that when I was in school. Have you heard of ELI the ICEman? E electromotive force (volts) L inductance (henrys) I current (amps) the I current (amps) C capacitance (farads) E electromotive force (volts) ELI the ICEman says; "In an inductive circuit the volts lead the amps and in a capacitive circuit the amps lead the volts." By 90 degrees, I think.
