Good afternoon everyone, I decided to write a short article. ABOUT new promotion people's mischief! These are devices for saving Electra energy, called Power Saver. In Russia, the price of these toys starts from 1000 rubles and reaches 20,000 TR, abroad the price starts from $3-$300. So what is the working principle? This toy or, as it is called, the device is placed near the meter at the input, swing close to it, based on the shortest length of the wire from the meter to the consumer. And supposedly this toy should reduce Electra energy consumption from 10% - you won’t believe it - to 50%. And with this scam, these devices can be offered for fabulous money everywhere!

Just out of curiosity, I bought such a device Power Energy Saver Electricity Save up to 35% EU 18KW,HOT! Free Shipping! . And lo and behold, after a bunk of weeks of waiting, I have it in my hands along with a brand new watt meter. I couldn’t take a video so I could give this toy to the village to confirm my fears. Which in the end was confirmed! At home the test went like this:

testing time 1 hour / halogen lamp 150 Watt / breeze heater 1000 Watt / breeze heater 2000 Watt / oil heater 3000 Watt / computer without load 250-300 Watt

Halogen lamp 130 watts - with a toy 131 watts (when warming up the lamp consumes less power, but consumes about 150 watts at start-up)

Breeze heater 1000 Watt - 890 Watt - with toy 870 Watt - (same situation)

Breeze heater 2000 Watt -1790 Watt - with toy 1790 Watt

Oil heater heater 3000 Watt - 2800 Watt - with a toy 2700 Watt (most likely it did not cool down well)

Computer 220-300 Watt - 280 Watt - with toy 275 Watt

In a long-term test of about 2 weeks, the difference was about +\- 5%, with such a small error the device can be said with confidence that it does not work!

The design of the device is so simple that the most expensive of these devices is the plastic case!

Please be careful and do not waste money on such Know-How that can be spent from 1 cake to 20 cakes :) It’s better to sweeten your life than to put it into someone’s wallet!

Oh yes, in the case there is a container into which 2 thin wires go, which, even if desired, cannot reduce the power by 35% from 18 kW! The container is filled with black epoxy, the circuit consists of 2 capacitors, one electrolyte connected through a diode, the second non-electrolyte connected through a resistance and a resistance.

And this is in the best case like mine, another person simply had 2 wires filled with epoxy and after the break there was nothing but resin there was not a single part there :) maybe resin is a material that saves electricity?!

There were a lot of working systems in Soviet times, for example stabilizers that actually maintained voltage! There were also all kinds network filters, which smoothed out the ripples from our networks. Schemes can be found in different sources. But there is not a word about saving, these are simply devices that remove incoming interference and impulses, producing a clean signal from the input from the panel. And devices, especially digital ones, easily convert a clean signal into the desired output signal, while consuming the same power, and not in jumps! which leads to energy savings of up to 15%.

Yes, I’ll add more for information. We live in the age of information, where electricity becomes more expensive every year, and appliances consume less and less, and people pay more and more! How is this possible, you ask!?! It’s very simple, there are jammers that are installed at substations, either dead or counterfeit, I’m not sure that anyone is looking at it. They are installed after the step-down transformer, if they are not working properly or they are not installed at all to reduce the cost of the network, this leads to strong voltage surges from minimum to maximum input voltage. They play the role of a smoothing filter and also remove ripples in the network, which Power Saver supposedly also removes. But there the unit weighs from 300-1600 kg and here it’s 100 grams. just funny!

Today another parcel arrived with the energy-saving digital device “Intelliworks SD-001” (19 kW). I’ll note right away that I don’t know how effective it will be. Below is a description --- Real savings in real life! More acute than ever modern world issues of energy saving... And with the constant increase in housing and communal services tariffs, the issues of their payment are acute...

Therefore, any energy-saving technologies are so important. Your budget will bring real savings A new product of modern technologies - the energy-saving device “Intelliworks”!
Really saves from 15 to 45% of consumed electricity!

The energy saving device uses modern electrical technology, actively monitors and improves the power factor of your electrical appliances. In addition, intelligent technology optimizes voltage and current, thus reducing active power, which allows you to save up to 35% on energy bills!
The device also acts as a voltage stabilizer, storing energy for up to 10 seconds during an instantaneous power surge. This in turn leads to a longer service life for electrical appliances!
Operating principle of the devices:

The energy-saving device “Intelliworks” is included in the circuit parallel to the load after the meter. Then the inductive currents oscillate between the windings (which have inductive reactance) and the static converter, rather than circulating through the AC network, between the transformer and the load. AC control and measurement elements pass active power from the network to the operating equipment, and direct reactive current to the load phase where it is required. The power factor is automatically stabilized at a level close to “1”.
The useful power will increase due to the conversion of re active power, in additional, active!

A little physics...

Losses are caused by a delay in the AC phase to the voltage phase in the presence of an inductive load, since loads in household networks are usually actively inductive (electric kettles, coffee makers, washing machines etc.). Active energy is converted into useful energy, and inductive (reactive) energy creates magnetic fields that form an additional load on the power line. Spreading throughout the network, this energy makes oscillatory movements from the load to the generator and back. The share of reactive power (depending on the type of payload) in the network can range from 15 to 45% of the total power.
The full power is taken into account by meters and payable - which means that if you exclude reactive power, you can save 15 - 45% of electricity, which is what the “smart intelligent” energy-saving device does!
What do we get?

Simplicity and ease of use and energy saving
power supply is improving,
heating of electrical wiring is reduced,
noise and vibration levels are reduced,
no harmful substances are formed electromagnetic radiation,
equipment service life increases,
protection of electrical appliances from voltage surges,

To the question Energy saving device asked by the author Alexander Tsibriy the best answer is Don't believe it. If it were so, then they would have been used in the energy sector long ago to reduce losses.

Answer from 2 answers[guru]

Hello! Here is a selection of topics with answers to your question: Energy-saving device

Answer from Yorgey Gavrilov[guru]
Yes, there is reactive power. In industry, reactors (capacitor banks) are used to compensate for this. But apartment meters only take into account active power (this is where the sellers of the device lie). Of course, reactive current creates additional load on the wires, which leads to some reduction in voltage. But in everyday life it is so insignificant that you won’t notice it. And it is impossible to realize compensation reactive current a capacitor of constant capacity, since the load changes. Conclusion: scam.

Answer from Serjik[active]
Energy-saving devices in which a capacitor is installed can potentially be effective in homes, BUT, according to statistics, they save no more than 1-5% of electricity, as they eliminate reactive losses that arise in household appliances only when turning on a vacuum cleaner, washing machine (not direct drive), or combine and so on. However, there are quite a few such consumers in the house and they are switched on rarely and not for long. It should be clear to everyone that reactive power is not generated by “every kettle” or incandescent lamp. Reactive power appears only when devices with a large inductive component - the winding - are turned on. These are transformers in power supplies and all kinds of electric motors. It is virtually impossible to see savings of even 5%, as monthly expenses differ by 10-30%. To calculate savings, a special technique is required that is capable of taking into account nonlinear loads, which are used by companies professionally engaged in the development and implementation of energy-saving devices, which are used for production purposes and successfully cope with their tasks when they are used locally after a comprehensive electrical audit.

When paying bills, especially after another tariff increase, many people think about the need to save electricity. The most meticulous among us go to the Internet and type in the search “how to save electricity” and then one after another they come across online stores offering a device for saving electricity. The temptation to buy a miracle device once, and then pay half as much for electricity for the rest of your life, is undoubtedly great, but doubt immediately creeps in - is this not a scam? Does the energy saving device actually work? Let's take a closer look.

What do manufacturers tell us?

The market and online stores now present so many similar devices that it’s dizzying and you don’t know which one to choose. As soon as manufacturers do not name their devices - economizers, energy savers, savers.

Let's look at how electricity is “saving” using the example of the energy-saving device “ELECTRICITY SAVING BOX”. Having gone to a website where they offer to purchase such a device (and even with a 50% discount), we learn from the first page that, it turns out, every second European family has already purchased such a savings device for their home, and is in full swing saving energy and money. Not a single store, office, auto repair shop, beauty salon, restaurant or residential building can do without it.

Additional benefits

The manufacturer indicates that the device not only saves energy, but also has a number of advantages:

1. There is no cheating of the meter, simply by connecting the device, energy is used more efficiently and an economic result is achieved.
2. The service life of electrical household appliances is extended.
3. Electromagnetic radiation harmful to humans that comes from electrical appliances and wiring is minimized.
4. The effectiveness of such a device is not unfounded; it has been confirmed by numerous studies and has a scientific explanation.

And using the device is easy and simple. It is enough to plug it into a power outlet, and after 1-2 months it will fully recoup the money spent, reducing the monthly payment for electricity by 30-50%.

Operating principle and device diagram

How do the instructions for its use explain the action of such a wonderful device?

Electricity consists of two components - active and reactive. Active energy is useful; it is what household appliances use to operate. Reactive energy is invisible, it creates additional load in the network. As a result, current consumption increases. Plus, reactive energy creates harmful electromagnetic fields. According to the manufacturer's instructions, the energy-saving device removes the reactive component from the network. Due to this, the current consumed by household appliances from the network is reduced. Accordingly, energy consumption and the cost of paying for it become lower.

Now let's see what the device circuit consists of so that it can actually provide such an economic effect. Outwardly, it looks quite nice - a silver plastic case, and on a black insert there is a shiny logo with the name of the company. Electrical contacts in the form of a plug are built into the housing. There are also one or two LEDs that indicate the device is on.

By unscrewing one screw that holds the two housing halves together, you can see a small electronic board with a minimum of components and a film capacitor (its capacity is small, about 6 microfarads). If you carefully study the circuit assembled on the board, it will become clear that it simply provides LED indication.

Testing the device

We have studied the entire device theoretically, all that remains is to test it in practice.

You should immediately pay attention to the meter readings, or even better, take control measurements. You need to write down the numbers on the meter, for example, at 9.00 today, then at the same time the next day and calculate what the consumption was for the day. It used to be more convenient to monitor the counters when their action was based on a rotating disk. Based on the rotation speed, it immediately became clear that the disk moves slower, which means less consumption, and accordingly vice versa. But now it’s unlikely that anywhere there will be a house or apartment with a disk meter; everywhere they were replaced with electronic ones a long time ago. So you have to record the readings and then make simple calculations.

After this, you need to plug the device into the outlet to save money. Device manufacturers recommend choosing the closest outlet from the meter, but you can plug it into the busiest one. The LEDs, as expected, lit up. Now you need to calculate the consumption for the next day with the device turned on (again you need to take the day from 9.00 today to 9.00 tomorrow for the reporting period). It is very important that the load connected to the network does not change. That is, let for this reporting period The same number of household appliances in your apartment (refrigerator, computer, TV, water heater, electric heating) will remain connected to the network so that you can evaluate the device in terms of efficiency for saving energy.

Unfortunately, it turns out that the meter accumulated the same kilowatt-hours as without the saving device turned on.

But many people, thinking that they are buying an electricity economizer, come home, take a bargain out of the package, plug it in and calmly begin to wait for the economic effect, and do not even look at the meter readings. After a month, when the time comes to pay for the consumed electricity, they are surprised to discover that the consumption has remained the same. Why did it happen? What's the catch with this device? Is this really another myth and a way to make money on gullible people?

To answer these questions, you first need to have a good understanding of the components of electricity. As mentioned above, it comes in two types.

Energy: active and reactive

pay attention to the melted capacitor - it is possible that such a miracle device will cause a fire

Active is the component of electricity that is spent on creating visible work. For example, the fan began to rotate, the pump began to pump water, the electric fireplace began to heat the air, the stereo began to play music, and the electric lighting lamps came on. That is, active electricity has accomplished useful work and transformed into light, sound or thermal energy. The active component is always measured in watts (W). Many electrical appliances in their operation are based only on this component - electric stoves and ovens, irons and heaters, incandescent lamps. If the passport says that the active power of the device is 1 kW, then such equipment will take the full power of 1 kVA from the network.

Reactive energy is called that because it is invisible. Many household appliances will not work without it, since the main unit in their operation is the engine. It, in turn, is set in motion by creating an electromagnetic field around it. And this is the main function of reactive electricity. Such household devices include a refrigerator and a washing machine available in each apartment, all types of power tools (grinders, electric drills, screwdrivers, wall chasers). This value is measured in vars (var).

To reduce electrical energy consumption, it is necessary to reduce its active and reactive components.

In the case of an active one, it is enough to turn off unnecessary consumers, that is, reduce the number of lighting lamps and electrical household appliances powered from the network.

Reactive energy is reduced by connecting quite powerful capacitors to the network, which compensate for it and reduce consumption. To correctly select such capacitors, you need to know the total power of all electrical devices connected to the network. Those 6 microfarads that are available on the film capacitor included in the device circuit for saving electricity are only enough to compensate for a small reactive power fluorescent lamp(40 W).

But the funny thing is that the amount of this compensated reactive power has absolutely no effect on anything. Active electricity meters are installed in our houses and apartments and they make absolutely no difference how much reactive energy passes through them. The household home meter does not count it.

Don't be fooled

The device we discussed above Chinese manufacturer I bothered to provide at least a small capacitor. The circuit of cheaper devices generally consists of LEDs and resistors. When plugged into the socket, two small indicators begin to glow, and you get something similar to garlands for a Christmas tree. But the garlands at least perform the function of decorating the New Year's holiday, and a device with two luminous points does not carry any functional significance at all.

Therefore, no matter how much we would like to disappoint those who have already bought similar energy-saving devices, we have to admit that this is a complete scam. While people are throwing away money to buy devices to save electricity (and they cost from 300 to 1,500 rubles), those who invented them are rubbing their hands with satisfaction. A very profitable business is to buy a batch of such boxes in China, increase the price 10 times and sell to gullible citizens.

Here is a detailed video report on ordering two different “economists” directly from China:

We hope this is enough to stop buying the device. And especially don’t try to come up with something on your own. Again, the Internet is full of articles, diagrams and videos on the topic of how to make a device to save electricity yourself. They even come up with such impudent names as “free electricity”. Do not fall for these tricks under any circumstances, a DIY “economizer” can, in the worst case, damage the electronic board of the meter, and in the best case scenario, it is simply wasted time and money.

How to save energy without a miracle device?

To add a little optimism, we want to give you real advice on how you can reduce energy consumption in a residential building:

1. Incandescent lamps can be replaced with fluorescent, energy-saving, and LED lamps. So simple, and the annual energy savings when replacing just 10 light bulbs will be about 800 kWh.
2. During the daytime, use more natural light. To do this, do not clutter the window sills with huge flower pots or hang dark curtains.
3. Install a multi-tariff electricity meter. The night rate is cheaper, so use the delayed start function in household appliances. Keep your dishwashers, washing machines, bread makers and multicookers running at night.
4. When installing lighting in an apartment, you should definitely find a place for hanging wall lamps and sconces, and small portable lamps. If you want to read or knit, turn them on and not the overhead lighting of the entire room.
5. During the day when you leave home and at night when you sleep, turn off televisions, computers, music centers, microwaves. All these electrical appliances also consume electricity in standby mode.
6. If possible, replace household appliances with new ones. The older she is, the higher her energy consumption. When purchasing, give preference to models with class A.
7. Before using the air conditioner, close all windows and doors and do not cool the street.
8. If you have electric heating, you should think about additional insulation of the apartment or house outside.
9. And, of course, when leaving, turn off the lights.

We hope that in this article we have clearly explained that by purchasing and installing such devices to save energy, you can only slightly relieve a small section of wiring from a tiny fraction of the reactive component. But the counter will not appreciate your efforts or the money you wasted. Do not mess with homemade devices, but rather use the advice and.

IN last years Many people try to save on utility bills. People install meters in the hope that they will have to pay less. Some people save money in everyday life.

A device called a “statistical converter” appeared on the Internet not long ago. Manufacturers advertise it as an energy-saving device. They say that thanks to the installation it is possible to reduce meter readings by 30% to 40%.

Energy saving device

It is believed that the unique technology is capable of stabilizing the power efficiency of the network and eliminating voltage surges. This results in a longer service life for electrical appliances.

The principle of operation of the device is as follows: parallel to the current current, the network is switched on. Inductive currents will oscillate between the converter and the windings, rather than walking between the load and the transformer. Alternating current passes power to the equipment, and reactive current goes where it is needed. certain moment. Thanks to the transformation of reactive power into active power, the latter increases.

Should you believe in a miracle or understand the device?

The prospect of paying less, of course, arouses interest among many. But I want to figure out whether the device really works miracles.

Even the description “intelligent technology” raises doubts. It immediately becomes clear that advertisers did a good job on the project. Compensation does happen. But how much does it save money?

It was decided to conduct experiments with one of the devices. Below is an analysis of one of them.

Experiments and measurements

The energy saving device is called Electricity Saving Box. In China the device is quite cheap. But for Russia, enterprising businessmen sell it at a much higher price. Both this and other similar devices have similar characteristics:

• voltage - from 90 to 250 V;
• network frequency - from 50 to 60 Hz.

For the experiment, a wattmeter and several electrical devices were used that will create the necessary load. Instead of a wattmeter, you can use any one. An incandescent lamp and a convection heater were used for the load.

Readings were taken from the device when it was turned on and from when it was turned off.

In the off state, measurements showed an active power of 1944 W.

The switched on energy-saving device Saving Box showed the same 1944 W at the output. From this it follows that there were no savings.

Another experiment can be carried out: a wattmeter is installed on the power cable. A vacuum cleaner is plugged into the outlet and the active power consumption is measured without an energy-saving device, and then the readings are recorded. The specialist conducting the experiment noted the following results:

• active power - 1053 W;
• power factor - 0.97;
• voltage - 221.3 V;
• total current - 4.899 A.

After this, with the device turned on, the same measurements were repeated. Happened:

• active power - 1053 W;
• power factor - 0.99;
• voltage - 221.8 V;
• total current - 4.791 A.

It can be seen how the value of the total current has decreased. However, the power factor increased by 0.2, and it is clear that the active current remained at the same level.

Electrical diagram of the device

If you look at this “unique” technology, you will discover a completely unexpected picture for such a serious device:

• fuse FU;
• 4.7 µF capacitor;
• diode bridge for voltage rectification;
• varistor

The capacitor is compensating. The same is mounted in throttling lamps to increase power. Nothing original.

Experts explain that the energy-saving device Electricity is an unregulated compensating type device with a power of up to 78.5 V Ar. It is not difficult to come to this value on your own. Enough to divide mains voltage, taken squared, by the capacitor reactance. The resulting value is strikingly different from the declared 15,000 W. Passport data is indicated in watts, apparently so that buyers do not understand anything.

A simple advertising trick

“How can this be?” many people will be surprised. After all, we saw with our own eyes in advertising videos how the readings actually changed when the devices were turned on. In the advertisement, they connected an electric motor and took readings without installing the device. Then the same was done with the device turned on. And the measurements showed completely different results!

However, this is nothing more than a trick, and it can be explained very simply, as experts say. The fact is that measurements are made in the usual way. But this way you can get the value of the total current in the network, which, naturally, is different.

But to calculate the active current, the total current value is multiplied by the load factor. That’s when the results will show different values: the total current indicator changes, but the active current indicator remains at the same level. This is proven by real measurement of active power using a wattmeter. And this, of course, is not done in advertising videos.

Accounting for active and reactive power

Individual meters take into account active power.

Energy-saving devices should reduce the reactive part of the current by connecting a compensating capacitor. But even if they perform their functions, this does not reduce payment costs, since household meters, in principle, can only take into account active energy consumption. Therefore, people who bought the device say that they do not observe any positive effect.

When it comes to industrial production, energy-saving technology can come in handy. After all, the meters here take into account both parts of the power: both active and reactive. Therefore, if energy costs reach a significant level, then capacitor banks help reduce losses. Such devices still operate today, reducing reactive power. But these are completely different devices that have nothing in common with the product being offered.

So it turns out that manufacturers are misleading consumers by selling a useless energy-saving device. Reviews with positive ratings are becoming less common online today. Apparently, the number of people who understand exactly how advertising calculations are made is increasing.
