The truth about energy saving devices

The cost of electricity is growing with enviable regularity, and the desire to save on bills for electricity is quite logical. There is a lot of work and quite legal ways to save on electricity, but are relatively new produced devices, which according to the advertisers, saves almost 30% of the total consumption. I purchased this machine and now want to tell you what really capable of this unit.

Appearance and device parameters

I chose the most common form of execution under the proud name Electricity Saving Box. I bought it in the online store at the price of RUB 234 with free shipping.

On the front side except for a pair of LEDs is no longer any indication. On the back side there is an information sticker to the product parameters.

The first thing I immediately caught my eye is that this device, designed as much as 30,000 watts. After all, we all know even from the school course in physics that P = I * U, it follows that I = P / U; 30,000 / 230 = 130.434 A. That is, this unit is designed for a current of 130 amperes.

We will not draw conclusions ahead of time and just assume that the manufacturer has released a product with dual power reserve.

Principle of operation

So now I want to say a few words about the principle of operation of this product. By the conviction of producers - advertisers are device works as follows:

During operation, product is converted reactive component of electric power to the active component, which is then given to the network.

In truth, in the networks really present both active and reactive power. But in the private sector are absolutely all electricity meters consider only the active part. That is, for the average consumer is absolutely no matter how much reactive power passed through his account of the instrument.

Reactive power is considered to be in the enterprises where there are large inductive loads. And there are installed meters for reactive component, as well as special compensating devices.

It turns out that the very principle of operation indicates a completely useless for home use. But let's see what's inside this priborchiki.

Internal organization

So, open the case, we opened here is a picture:

Here, apart from current limiting resistors, a pair of light-emitting diodes and black boxes unmarked (probably just a capacitor) is no longer absolutely nothing. By and large, the device only to power the LED circuit it.

And this assembly has no relation to the reactive power compensation. Moreover the appliance will be an additional source of power consumption. Yes, this consumption will be negligible, but it will.

But let's move from the theoretical analysis to the real test and verify, and suddenly the economy really is.

The real test of the device

So, again, back to the advertising device and check how it compensates for the reactive component of power. For this we need a normal bulb and a drill (or other load), extension, and any device to measure the strength of the current in my case is a digital power meter Hidance H3680W, I I bought here.

We are putting our verification scheme and begin the measurement. The results can be seen in the video.

Summary and Conclusions

So, what I want to say about this device: as a means to save energy, it is absolutely useless. So do not waste your money on the purchase of this product, there will be no sense of it.

And this applies to all similar products, not only to the specific model. If the article was useful to you, you will appreciate it Like, it will show the article to as many people, and perhaps someone else will save from senseless waste of money. Thanks for attention!
