How to tell if there is a problem with the energy meter in operation

There are two ways to test the accuracy of the meter:

1. It is sent to the Technical Supervision Bureau for the effectiveness of the meter;

2. It is a self-test at home.

Here's how:

1. Observe the flashing of the pulse indicator on the electric surface disk.

Cut off the main switch in the distribution box at home or unplug all electrical equipment at home, after confirming that there is no equipment in the electricity, observe the flashing of the pulse indicator light on the electrical surface disk, generally within 10 minutes without flashing or only flashing 1 time, the meter is running normally. If the indicator flashes multiple times, the meter is not operating properly.

2. Calculate and judge the value of the total electricity, peak electricity and valley electricity displayed by the transcription meter.

At the same time, the total electricity, peak electricity and valley electricity values displayed by the meter are copied, such as when the value of the peak electricity and the valley electricity are equal to the total electricity, the meter measurement is normal, and vice versa.

In our daily life, many people will have different types of electricity meters at home, some old-fashioned meters, some are installed first, so there will be various problems in the use of the meter, how can we detect whether the meter is normal? Today, I will tell you how to see if there is a problem with the meter, I hope it can help you.

1. How to check whether there is a problem with the meter.

1. When we inspect it, we must pay attention to pull off the main gate of the distribution meter, and then look at whether the indicator light on the meter is flashing, if it only flashes for 10 minutes or does not flash all the time, it means that the meter is normal.

2. If the meter indicator light at home keeps flashing, it means that the meter is faulty.

3. We can also turn off all the electrical equipment at home, leaving only a stable electrical appliance on it, to see if the meter is almost the same after an hour, if there is a particularly big difference, then it means that the meter is faulty, it is recommended to find professional personnel to overhaul, otherwise it will bring us certain economic losses when paying the electricity bill.

2. What are the tips for using electricity to save electricity?

1. When we use electricity, we can choose some energy-saving lamps, such as LED lights, and now few people will use electric light bulbs at home, because light bulbs are very power-consuming.

2. In addition, we should also pay attention when buying LED energy-saving lamps, not necessarily the LED lamps on the market are energy-saving lamps, but also to ensure its quality and brand reputation.

3. Summer is the peak period for using air conditioning, many young people will turn on the air conditioning all day long, in fact, air conditioning is very power-consuming, it is recommended that the air conditioning should not be too low at about 25 degrees, the lower the air conditioner plays, the more power consumption.

The above is a summary of the relevant content and information about what to see if there is a problem with the meter, I hope it can help you, if you have other questions, you can leave a message below the platform, and you will solve the problem in time. Finally, if you have any questions about home furnishing or home decoration, you can pay more attention to Qeeka Home.

Check if the meter is normal:

1. Observe the flashing of the pulse indicator on the dashboard.

Cut off the main switch in the distribution box or unplug all appliances in your home. After confirming that there is no power supply to the device, observe whether the pulse indicator on the electrical panel flashes. Usually, it doesn't blink or only blinks once in 10 minutes.

The instrument is working fine. If the indicator flashes a few times, it means that the meter is not working properly.

2. The meter reading shows the calculation and judgment of the total power, peak and valley power.

The total, peak and valley power displayed by the meter should be recorded at the same time. When the sum of peak power and valley power is equal to the total power, the meter measurement is normal, otherwise it is abnormal.

3. Turn on the electrical equipment with a relatively stable power supply and observe the measured value of the meter.

Turn off all the electrical devices in the home, record the degree displayed by the meter, turn on the electric water heater or induction cooker for a while, and then turn it off, record the degree displayed by the meter at this time, and then subtract two degrees to obtain the power consumption of the newly turned on device; The amount of electricity consumed by the device is calculated based on the power indicated on the device's nameplate and compared to the amount of electricity recorded by the meter to determine if the meter measurement is correct.

There are several levels of accuracy for mechanical meters:

At the same time, temperature, voltage, frequency, voltage and current waveform, working position can be caused.

Error. The accuracy level is: Table, permissible deviation from the standard temperature of 2

The accuracy level is: table, allowable deviation of rated voltage.

Target. The accuracy level is: 1 of the number of dates with the allowable deviation rated voltage. The accuracy level is: the table of allowable deviations from the rated voltage.

The accuracy class is: the table of the allowable deviation of the rated frequency. The accuracy class is: the table of the allowable deviation of the rated frequency. The accuracy class is: the table of the allowable deviation of the rated frequency.

The accuracy level is: The distortion of the permissible deviation voltage and current waveform is not greater than 1. The accuracy level is:

The allowable deviation of the distortion of the voltage and current waveform is not greater than 2. The accuracy level is: the distortion of the allowable deviation voltage and current waveform of the stool head is not greater than 3.

The accuracy level is: The distortion of the permissible deviation voltage and current waveform is not greater than 5.

The accuracy level is: The table allows the installation of the inclination angle not greater. The accuracy class is: The table allows the installation to be tilted at an angle of not more than 1°.

The accuracy level of the electronic meter is: several kinds of celebrations. External factors affecting the error can not be noted.

The absolute value of the amount of change in the meter over a 24-hour period.

It must not exceed 1 5 of the basic error.

Therefore, if your meter is in standard installation and use, if it is an accuracy level above the meter, then it is normal.

Nowadays, people can't do without electrical appliances at home, and some electrical appliances consume a lot of electricity, such as air conditioners, water heaters, floor heating, etc., in the process of use, unconsciously generate huge electricity bills, and some owners even think that there is a problem with the meter. So, how do you check if the meter is working?

1. Pull down the main gate in the distribution box and see the flashing of the indicator light on the meter of the electric judgment mu.

2. If it does not flash or only flashes once within 10 minutes, the meter is normal, or all the electrical equipment at home is turned off, leaving only a more stable electrical appliance to run, and see whether the electricity consumption for one hour is consistent with the metering.

3. If there is a transaction discrepancy, it means that the meter is faulty, and it is recommended to find a special person to check it.

The above is the introduction of how to check whether there is a problem with the meter, I don't know if netizens understand?

How do I check if there is a problem with my meter? How to check whether there is a problem with the meter 1, observe the flashing of the pulse indicator light on the electric surface disk, cut off the main switch in the distribution box at home or unplug all the electrical equipment at home, and determine that there is no equipment in the electricity After the electricity is used, observe the flashing of the pulse indicator on the electric surface disk, generally within 10 minutes without flashing or only flashing 1 time, the meter is running normally. If the indicator flashes multiple times, the meter is not operating properly.

2. Calculate and judge the total electricity, peak electricity and valley electricity values displayed by the transcription meter at the same time, such as when the value of the peak electricity and the valley electricity is equal to the total electricity, the meter measurement is normal, and vice versa. 3. Turn on an electrical equipment with relatively stable power to observe the metering value of the meter, turn off all the electrical equipment at home, record the degree displayed by the meter, turn on an electric water heater or induction cooker for a period of time and turn it off, record the degree displayed by the meter at this time, and subtract the two degrees to get the power consumption of the equipment just turned on. According to the power marked on the nameplate of the equipment, the power consumed by the equipment is calculated and compared with the electricity recorded by the meter to determine whether the meter measurement is normal.
