Rumors debunked! Power savers really can’t save electricity bills, don’t be fooled again!

Power Saver, a power saving device that claims to save up to 40% of electricity.

Not only that, the editor has seen that some e-commerce platforms are also selling energy-saving devices. If you look at any one of them, you will see tens of thousands of people paying for them. There are even purchase reviews and electricity bills showing that their families have saved more than 100 kWh of electricity after using them.

The editor can't help but ask, can using a power saver really save so much electricity?

In order to verify whether the power saver really saves electricity, the editor of this issue of Electric Power Intelligence Bureau specially purchased power savers of different prices and came to the Energy Efficiency Innovation Laboratory of State Grid Zhejiang Electric Power Co., Ltd. to completely unveil the mystery of the power saver!

Next, let’s take a look at the power saving experiment to see if it can save electricity!

To ensure the accuracy of the experiment, we will measure three types of electrical appliances with different properties (inductance, capacitance, and resistance) separately.

Experimental content:

① Turn on the heater (resistive load), computer (capacitive load), and electric fan (inductive load) respectively, and measure their power consumption for one hour;

② Then connect the power saver and measure their power consumption for one hour;

③ Turn on the three devices at the same time and measure their power consumption for one hour;

④ Then connect the power savers and measure their power consumption for one hour.

Four sets of data were obtained for comparison.

Experimental results: Through data comparison, it was found that the power consumption did not decrease. This shows that the power saver did not save power after it was connected.

In order to continue exploring the secrets of the power saver, the experimenters also disassembled a set of power savers.

We found that the main body of these power savers is actually a few capacitors and a circuit board ;

After the power saver is connected to the circuit, the capacitor starts to work, but it can only improve the power factor but cannot reduce the consumption of active power.

You should know that the household electricity bill settlement only calculates the active power consumption. After the power saver is connected, the power consumption of the circuit board will increase.

If used for a long time, not only will it fail to save electricity, but it will also increase extra electricity bills.

At the same time, we also found that in some areas, there were fraud gangs that illegally modified electricity meters under the guise of energy conservation and consumption reduction.

Violators used illegal means to modify the electricity meter under the guise of sales promotion, causing the meter's error to change drastically during the measurement process, thereby interfering with the measurement data.

For this purpose, we also conducted experiments on modifying the electricity meter.

Experimental content:

A heater was used as the experimental object. The heater was turned on and the electricity consumption was measured 1 hour before and after the electricity meter was illegally modified, and the measured data were compared.

Experimental results: After illegally modifying the energy meter, the power consumption will indeed decrease. But the editor reminds you that this modification method is illegal !

According to Article 71 of the Electricity Law of the People's Republic of China , anyone who steals electricity shall be ordered by the power management department to stop the illegal behavior, recover the electricity charges and impose a fine of no more than five times the payable electricity charges. If the act constitutes a crime, criminal liability shall be pursued in accordance with the relevant provisions of the Criminal Law.

In fact, in our daily household electricity use, as long as we can develop good electricity usage habits, turn off electrical switches in time, unplug electrical appliances, and do not leave electrical appliances in standby mode for a long time, we can reduce some electricity consumption and save a lot of money over time.

Remind you again: selling fake energy savers online, or illegally modifying the energy meter under the guise of selling energy savers, stealing electricity and other illegal activities are not advisable!!!
