Why does the electric meter run so fast?

Question 1: Does the electric meter run very fast for any reason? I was really exhausted trying to figure this out.

When I pay the electricity bill at the end of the month, it shows more than 800 kilowatt hours per month. When I look at the bill, my head goes "buzzing". I only use a few electrical appliances at home. I estimate that I only use one or two kilowatt hours per month. Why? There would be so many kilowatt-hours of electricity, because it was newly renovated, so I quickly found the renovation electrician to find out the cause. The electrician checked the electric meter and used a clamp-type flow meter to connect the incoming and outgoing wires. It showed 7 Anders, but when I looked at the number after the decimal point on the electronic meter, "Huh?" It jumped like "hoo", and it jumped 1 degree in 5 minutes. It really scared me. After checking here, the electrician concluded that there was something wrong with the meter.

I called the Power Supply Bureau to report for repair and asked for the meter to be removed. The staff of the Power Supply Bureau had a hard time waiting. After waiting for several days, they finally came to remove the meter. To be on the safe side, I went to the Measurement Center of the Municipal Power Supply Bureau with the staff. When I calibrated the meter, the calibration result was not what I wanted to see. The positive and negative error of the meter showed 0.02. The inspector said the meter was of very good quality. I told my doubts to the inspector, and he said that there would be nothing wrong with the instrument testing. If you were not sure, you could go to the municipal quality inspection department for verification. I had no choice but to go to the Municipal Metrology Institute for testing again. The Metrology Institute charged me 30 yuan. The inspector and I went to the inspection room. The old man doing the inspection seemed to be very serious and turned off the air conditioner in the room. After opening it and waiting for a long time, they were told that the room temperature must reach 20 degrees before the test could be done. They also said that it was not cost-effective to do this test. I could only nod my head in agreement. The final test result was still the same. It was a qualified electric meter. The old man also helped me analyze it. If there is no problem with the electric meter, there must be a problem with your home's wiring.

Can I not believe that the results of the two inspection departments are the same? I also asked several electricians, including those in the bar, whether the speed of the meter was related to the flow rate. They all said yes, but when it came to the results from the inspection department, they were ambiguous. I had no choice but to find an experienced electrician to continue checking the wiring. After checking again and again, it was still the same. There was no problem with the wiring. I'm in a hurry! There is no problem with the meter and the wiring. What is the problem? Could it be that there is a ghost? I sat at home and thought about it for a long time, and finally came up with a solution. I took the newly purchased induction cooker to the meter box and connected it to the induction cooker from the outlet of my electric meter (the household wire was cut off). The 1500-watt induction cooker ran in 5 minutes. 0.8 degrees. So I connected another person's home appliance meter, and it ran 0.2 degrees in 5 minutes. This happened to several houses I tried. Now I feel confident that there will be nothing wrong with this test. At the same time, I also felt very angry. What kind of tests did the quality inspection department do? It was simply a scam.

At this time, I also recalled that when the quality inspection department tests electronic meters, it tests whether the pulses of the electric meters are normal. When testing the wiring, it connects to the pulse end of the electric meter, and the numbers on the electric meter will not move. So I thought maybe the electronic watch converts electric current into pulses to drive the mechanical part of the watch to rotate. When the electric meter is accidentally shaken before installation, the mechanical part may be damaged, but the pulses are still normal. After finding out the reason, I confidently went to the leader of the Measurement Center of the Power Supply Bureau and expressed my doubts. The leader was quite experienced and agreed with my idea, and promised to measure on site and refund the electricity bill if the situation was found to be true.

This incident has been successfully resolved, but I still feel uncomfortable. When the quality inspection department identified the problem, they only knew how to do it behind closed doors and only looked at the instrument, but did not know how to comprehensively analyze the problems with the meter. It can only measure the deviation of the pulse of the electric meter under normal circumstances. If the pulse exceeds the standard, it is good, otherwise it is bad. This kind of identification is not complete. It is obviously a faulty electric meter, but it is said to be a good meter without problems, which is harmful. It hurts me so much. To this end, I will report or complain to the relevant units in appropriate ways.

I will write down my annoying experience for my friends in the forum to read, so that they can have reference solutions for similar problems in the future. Thank you for your attention!

Question 2: Why does the new meter run so fast? Since the introduction of smart meters, there has been a cry across the country that it generally feels like the old meters are running faster than before.

The user feels that the meter is going faster for the following reasons: One reason: The new smart meter is more sensitive and more accurate than the mechanical watch. The previous mechanical watch has been used for a long time, and there will be certain wear and error. At the same time, the old mechanical watch needs a certain amount of time. In the past, if the plug was not pulled out and the TV was on standby, the electric meter might not run. But now the new electric meter relies on pulse numbers to display, and it is very accurate. Home appliances will run even if the plug is not pulled out, so residents feel that the starting current is running faster than before. Hurry. Reason two: The current rated current of the electricity meter provided by the electric power department is 5 (60) A. The numbers in brackets are the short-time allowable overload current. The current of a 1200W electric kettle is 1200W/220V= 5.4A. The current of just one electric kettle exceeds the normal working current of the electric meter. Adding in other electrical appliances, the current in many households exceeds the normal working current of the electric meter for more than half of the time. 5A ***. Once it exceeds this ***, the meter reading will spin rapidly at several times the normal value. In the end, you will have to pay more for electricity every month. Why does the power supply bureau not provide large electricity meters with normal operating currents of 15, 20, 30, and 40A, but only provides 5A *** electricity meters? This is where the trouble lies. Reason three: The increase in voltage also speeds up the meter. The voltage on the line fluctuates within a certain range. If the voltage of 220V fluctuates to 237V, it is within the normal range. However, when the voltage is high, the meter will move faster. If some unscrupulous person controls the voltage a little, the electricity consumption of residents will increase greatly. The fourth reason is the distrust of the power sector as a monopoly. As a monopoly, the state electric power department takes over the operation of electricity and the installation, calibration and maintenance of user meters.

Question 3: I feel that the electric meter at home is running very fast. What’s going on? 1. If the electric meter is in a meter box, you can change the electric circuit of other people’s electricity and connect it to your electric meter. However, This conflict is rare or even non-existent now. Unless your electrician has a brain problem or has a deep grudge against you, because this is a matter of losing his job.

2. For experienced electricians, the operation in step 1 above does not require a power outage. Just connect someone else's wire to your meter. Anyone with a little bit of experience can spot the problem from the wiring.

3. Some kind of device makes the meter faster. I have been in the industry for more than 10 years and I have never heard of it in my place, but there are some that make it slower. This device is generally useful for mechanical watches, but not for electronic watches. And those that don’t have a large amount of electricity are generally not used.

4. The electric meter has no pointer and is rotated internally by an electric meter gear. Generally, no one touches the meter. You can check this yourself. There are two lead lumps on the meter, one is the factory lead seal, and the other is the inspection seal from the local power supply department. If these two things are not there, then Prove your meter was turned on. There are also some watches that only have a factory seal.

Question 4: Why does the smart meter run faster than the ordinary meter? Because it is more accurate and can measure electricity consumption even with a small amount of current.

Question 5: Why does the smart meter run so fast? According to you The electrical appliances you use can calculate your electricity consumption

The computer calculates 300W (with monitor) 0.3 X 4=1.2kWh

The fan 50W 0.05 >

There are 1.45 kilowatt-hours of electricity here. Including mobile phone charging and other things, the meter went from 8.6 to 9.8 in one night, which is only 1.2 kilowatt-hours of electricity. It is normal!

Moreover, the electricity meters are all tested and sealed by the metering center of the electric power department, so it is difficult to tamper with them.

Question 6: Why does the new electricity meter "go fast"? Customers who have installed new meters reported that the new electricity meter "goes fast". The reason is that the old electricity meter uses mechanical principles to measure and has less sensitivity at light loads. Low, the electricity under low load and light load conditions cannot be measured accurately. When the charger or electrical equipment is used at home, the current generated is weak, and there is a phenomenon of missing meter; and as the running time increases, the meter will generally Going slower and slower, the error keeps increasing.

The new type of electric energy meter is based on the principle of digital circuits, has accurate measurement, high sensitivity, strong reliability and good stability, and can accurately measure electricity under various load postures. Residential users are hereby reminded not to leave household appliances in standby mode for long periods of time when not in use to avoid unnecessary electricity bills and save energy. The manufacturing standards and functional standards of new electric energy meters are formulated in accordance with relevant national regulations, and they are all national products approved by the Technical Supervision Bureau. We have strict requirements on the quality of electric energy meters. Sample meters have been inspected by the National Instrument Inspection Center, and products supplied in batches have undergone full performance testing by provincial and municipal measurement centers to ensure accurate and reliable measurement errors. If residents who use electricity have questions about the accuracy of their own electric energy meters, according to Article 79 of the country's "Power Supply Business Rules", they can go directly to the affiliated power supply bureau to apply for calibration. Electricity customers must first pay for electric energy meter calibration according to regulations. For a fee, the staff will go to the site under your supervision to remove the meter, seal it, and send it to the Electric Energy Measurement and Testing Center for inspection. If the electric energy meter is confirmed to be qualified through verification, the customer shall bear the verification fee; if the error of the electric energy meter is confirmed to exceed the allowable value stipulated in national standards, the customer's verification fee will be refunded, and the power supply department shall bear the verification fee and issue a notice of verification results at the same time. The power supply department will refund the excess electricity bills paid by users in accordance with the law. During the period when users apply for meter inspection, their electricity bills should still be paid on time. After the meter inspection results are confirmed, the electricity bills will be refunded. If the user still has objections to the inspection results, he or she may apply to the technical supervision administrative department for arbitration. The Provincial Institute of Metrology, Verification and Testing is the highest authoritative institution in the metrology profession in Heilongjiang Province.

Question 7: My electrical meter seems to be running too fast. Don’t comment on the feeling. Test it yourself: turn off all electrical appliances, and only connect one high-power electrical appliance with a known wattage, such as a rice cooker. , it takes an hour to read a few words, and you can also count the number of pulse lights flashing on the meter in 10 minutes to judge. If the test results show that there is a problem with the meter, you can apply to the management department to replace the meter.

Question 8: What is the reason why the electric meter runs too fast? Haha, these are all psychological feelings. All countries with electric meters have been inspected and shipped from the factory. In today's society, there are many more electrical appliances than before. Of course, if the electric meter runs too fast, it is the best psychology. The slower the better, no matter how you use it, it is best to use one kilowatt-hour of electricity a day, Lao Bai will think so, but this is not the case. The less electricity is used, the smaller the power. The greater the power, the faster the electric meter will be. The old electric meter dial uses more electricity. The indicator light of a new meter flashes quickly when it uses more electricity. It won't run without electricity, and it will run slowly when it uses less electricity. If you have no choice but to save a little if you are afraid of using too much, use less air conditioners, heaters, and water heaters. Use less high-power home appliances and save electricity, don’t you think?

Question 9: Why does the electric meter run so fast? If you don't use high-power electrical appliances, your home's daily electricity consumption will produce many more kilowatt-hours of electricity, which is obviously problematic. First, you can check whether the meter reader made a mistake or read the wrong meter (look at the meter he read last month and the current meter in your home). Second, you can check whether your electrical meter is leaking or being damaged. Others are stealing electricity (turn off all the electrical appliances in your home and see if your electrical meter is still running). Third, you can ask a professional to check whether your electrical meter is faulty (most experienced electricians should understand this). If you find the problem, it will be easy to solve. I suggest you ask the electricity bureau to send someone to check the problem. It is best to replace the meter.

Question 10: The meter runs very fast. Is there something wrong with it? In response to your question, please refer to the link you added below. I would like to explain the following points:

1. The electricity meter in your store is several times faster than the electricity meter in other places. Could it be that you are the one? There are more electrical appliances used in the store than in other places. Is there a fault in the wiring here and leakage of electricity? Is it because the employees are not well trained and the employees in the store are not aware enough of saving electricity, resulting in a waste of electricity? situation occurs.

2. It is possible that the accuracy of your electric meter is inaccurate. It is impossible for any company to guarantee that every piece of the product is 100% normal, and some malfunctions are also possible.

If you suspect there is a problem with the meter, you can complain directly to the electricity department that has jurisdiction over you and ask for meter inspection. It is indeed an accuracy issue. They will reimburse you the difference. If there is no problem with the meter, you will need to pay for the meter inspection in Ghana, so it is best to do it yourself first. Make a preliminary judgment.

As for whether the electric meter is accurate, you can refer to my answer to this question: The electric meter runs ridiculously fast. What instrument is used to measure the actual electricity consumption per unit time? (The writing is rather verbose. If you want to avoid wasting money, you should be more patient, haha).

3. In addition, if there is indeed a problem with the meter, you can contact Shengfan’s after-sales service department (download Shengfan’s website from Baidu, it is best to report it to your power supply company. On the one hand, if If there is indeed a problem, it can be recognized by the power supply company and it can make up for your losses.

On the other hand, they are usually busy and may not be able to go to the scene to deal with it in time.) As for your fear that they will be tricked, you can rest assured. , explained later.

Let’s take a look at the post in the supplementary part of the question. You can tell at a glance that it was posted by an outsider.

Article 1: First of all, Hubei Electric Power sets its own standards. In fact, the standards of various provinces in the country are different. They all put forward some requirements based on their own needs, either functionally or In terms of hardware performance, for example, Heilongjiang has higher requirements for low-temperature performance, while Hainan, Guangdong, and Fujian may have requirements for moisture-proof, salt-spray-proof performance, etc. As an electric meter manufacturer, or to put it bluntly, as a staff member working in an electric meter company, I naturally hope that the standards in all places will be consistent, so that changes will not be made all day long and increase the workload.

As for the saying that "all watch manufacturers are trying their best to build relationships to be shortlisted", I believe that is for sure. If the products cannot be sold, how can the company survive? I'm not very clear about the bidding process. I'm just more confident in the performance of the electricity meters that go out.

Article 2: Purchasing counterfeit electricity meters, "None of the meters produced by the manufacturer according to the electricity requirements has obtained a production license. And none has passed the inspection by the intermediary agency." This is nonsense. It is definitely impossible to produce without a production license. Thinking of those days of working overtime and repeated tests to ensure that the performance of the samples submitted for inspection passed the National Grid test, these words make me feel embarrassed. It is possible to find other companies to do OEM work. Think about it, Apple still looks to Foxconn for OEM work. Since they are specialized in the industry, quality assurance and after-sales service will definitely be no problem.

Article 3: "Meter measurement distortion", I don't know very well how people in the power supply department do it, but after dealing with them some times, I found that they are very lazy, and the current smart meters cannot be adjusted. Accuracy is very difficult without some skills. The traditional adjustment of resistors makes a very small change. I think they are too lazy to adjust the accuracy of the meter as mentioned here. Besides, this risk is very high, and a knowledgeable person can easily find it out by doing some calculations. After all, it is something that people across the country are supervising, and there are many competitors. Others can just verify and report it. Moreover, an electric meter must undergo at least three strict tests before it leaves the factory and is officially installed in the user's home. To put it bluntly, the possibility of tampering is almost zero. In fact, there are so many places where you want to make money, why bother in this most eye-catching place. . . .

Article 4: It is necessary to mention this article. The so-called "electricity meter that steals electricity from users" is yes. As a device for measuring electric energy, it consumes a part of electric energy like other electrical appliances. In fact This part of the electric energy is calculated into the loss of the transmission line and is not measured by the electric meter. This is paid by the power supply company.

The power consumption of the so-called 485 communication chip is actually very small. Your TV was turned off after watching the TV without unplugging it for an hour.

The power used is probably enough to last 10 No problem for a few years.

Article 5: Shengfan has always adhered to the concept of "energy saving, environmental protection, and innovation". Low power consumption and high precision are one of Shengfan's biggest selling points. The power consumption has always been several times lower than the national standard, and it is also much ahead of the industry. This can be verified.

We have already obtained many products...gt;gt;
