Anonymous users2024-02-12A qualified electronic meter will not have the above phenomenon. This is because there is a detection of magnetic field interference in the detection of the meter. However, it is not excluded that the small meter factory has made changes to the design of the meter in the subsequent production process, because of the lack of corresponding testing equipment and the prototype test has not been sent to the Quality Inspection Bureau for testing and illegal production.
1.The cost of testing by the Quality Inspection Bureau is very expensive. 2.
Detection equipment for electricity meters is also expensive. There are about 600 domestic watch factories, and only a handful can have a full set of testing equipment.
I have worked as a development and testing engineer in a first-class enterprise in the domestic meter industry for many years. To be sure, the magnetic field has little effect on the accuracy of the meter, at least our company has not found such a case. In addition, the testing of metered products is really, really rigorous.

Anonymous users2024-02-11The base station is very power-hungry, because it works 24 hours a day, and the annual electricity bill is easily tens of thousands. But it shouldn't be the magnetic field. The total meter and the sub-meter are not counted, and you have not counted the electricity meter of the base station.

Anonymous users2024-02-09It should not have an impact on the speed of the meter, the current electronic energy meter has a strong ability to resist electromagnetic interference, and the meter has a special item to detect the impact of electromagnetic radiation sources such as mobile base stations on the accuracy of the meter when doing the type test. According to the requirements of the standard, the error difference of the meter should not be greater than 2% under the harsh 10V m conditions, if the landlord is still suspicious, you can consult the power department whether this test has been done.

Anonymous users2024-02-07The base station is generally equipped with a dynamic loop monitoring, in which a smart meter that monitors the status of the mains can collect current, voltage and power, and you can know how much electricity each base station uses through the dynamic loop system. After conversion, it is the electricity bill. Not enough, generally not allowed to be used only for reference.

The meter is not an electrical device, it is just a meter to measure the amount of electricity consumed, how can it affect your electricity consumption... >>>More
I think it depends on the situation, some children love beauty, like to dress up and dress beautifully. For this kind of child, there is definitely an impact. It can be said that if the child's dressing requirements are met, she may be very happy, and she will be satisfied, so she will naturally turn her mind to learning. >>>More

The recent pork ** problem has also caused a series of people's repercussions, with the emergence of the epidemic, but also made a lot of items have been affected to a certain extent, the price increase of pork has made people buy appropriately, I believe that many people will be overly panicked after seeing the pork ** rise, so the emergence of the price increase is bound to affect the sales of pork, there is no good economy during the epidemic, and the problem of price increase has become a problem that people are embarrassed to do now. And with the emergence of pork**, many people also claim that if it continues to rise, they will not be able to afford pork in the future. And for the emergence of such a thing, it is bound to cause other meat ****, because with the current price of **, many people will choose a series of substitution behaviors, just like the current pork**, many people will choose to use chicken to replace pork This situation, and in the context of this phenomenon, it will inevitably cause a decrease in pork sales, after all, in this society, who doesn't want to save it? >>>More
