The meter of the transformer is wired correctly, why not go

Disconnect all circuits and find the cause one level at a time, preferably in detail.

Let the meter go fast?? Could it be that the power station generates electricity?

stealing (stealing) electricity; Divided into 1Energy meters.

Stop-and-go, 2...The energy meter is reversed, 3...The energy meter goes slowly. There are more than 10 methods, but there are no of the above methods. But stealing (stealing) electricity is a shameful act, and stealing (stealing) electricity at the same time is not undetectable! stealing (stealing) electricity; Don't even think about it.

Hello, a meter with a transformer will also reverse without load, this cannot happen. Because there is no current without load, there is no current ammeter.

It is not measured.

If you think my promise is helpful to you,.

When the ordinary meter is wired, it is sufficient.

If the meter itself has a fixed ratio, divide the reading by the ratio to get the actual kilowatt-hour.

At present, the maximum of the pass-through meter (without transformer) is 80A, and the maximum is 100A, and the current transformer is used if it is exceeded.

, but some of the current does not exceed 80A, such as 60A also uses 75 5 current transformers, mainly considering the wiring, that is, the wiring capacity in the meter is virtually connected, so add the transformer.

It is normal for there to be some difference between the master table and the sub-table, because there is a difference in sensitivity and accuracy between the large table and the small table. However, a difference of about 200 degrees a day is abnormal, even if it is used continuously for 10 hours a day, there is a 20 kilowatt electricity load, it is impossible for the family to have such a large load, I suspect, or the family has private production equipment.

Analysis of the reasons why the meter does not go;

1.The mechanical energy meter turntable is rotating, the electronic meter pulse light has a flash, the reading does not go out of words, and the integrator is faulty, 2The turntable of the loaded mechanical electric energy meter does not rotate, and the pulse light of the electronic meter does not flash, and the voltage coil may be lost or the voltage coil burns out the open circuit or the voltage sampling board fails, 3

Two elements one of the reverse polarity, 4Three-element polarity, one positive, one negative and one loss of voltage, 5There was no electricity at all.

Summary. 1. Wiring error, 2. Accumulation calculator or current or voltage acquisition failure, 3. No load.

The three-phase four-wire electronic meter is connected to the meter through the transformer, what is the reason why the meter does not go out of words?

1. Wiring error, 2. Accumulation calculator or current or voltage acquisition failure, 3. No load.

1. Check whether the voltage line is connected reliably and whether it is confused with the current line phase sequence; 2. Check whether the threading direction of the primary line of the transformer is correct and consistent; 3. Whether the meter is installed too large and whether the transformer is installed too large. (The meter is generally installed, because the current on the secondary side of the transformer generally does not exceed the current of 5A).

Three-phase four-wire electronic active energy meterA three-phase four-wire electronic active energy meter, including an electric energy meter, a single special element, a voltage sampling unit, a current sampling unit and a power supply. It is mainly used in the three-phase power grid with a reference frequency of 50Hz (or 60Hz) to measure the power of three-phase residential users and small industrial and commercial users. This series of products has good anti-electromagnetic interference, long service life, high accuracy and reliability, wide load, low power consumption, small size, light weight, easy installation, and anti-theft function.

Installation and use 1, the electric energy meter is installed in the indoor or outdoor meter box, the installation base should be fixed on a solid fire-resistant wall, there is no corrosive gas in the air, it is recommended that the installation height is during the installation process, if the machine is violently impacted or the shell is obviously damaged when falling from a high altitude, do not install, power on, and contact the first business as soon as possible. 3. The electric energy meter should be wired according to the wiring diagram, and it is best to use copper wire or copper terminal to access.

Hello, caused a measurement error. If the meter is not connected to the neutral line, the voltage measurement element of the meter will not work normally, which will have a great negative impact on the metering. This practice of not connecting to the neutral line is also strictly prohibited by the electricity charging department.

Absolute balance of three-phase load is possible, but it is difficult to achieve absolute balance of three-phase load, then there will be differences in three-phase voltage, the neutral point of the voltage coil of the three-phase four-wire meter is not zero, the measurement will be inaccurate, and it is appropriate to access the zero line. If the watt-hour meter only enters the live wire and does not enter the neutral line, the dial will not turn. Because the zero line is not connected, relying solely on the magnetic induction generated by the current coil, the dial has no rotating torque, (the analogy is like a single-phase motor without a starting coil), therefore, the watt-hour meter must be energized at the same time as the current coil, and the zero line is turned on, so that the voltage coil in the meter can get a voltage of 220 volts, and the dial has a rotating torque and rotation counting.

Extended information: Precautions when connecting the three-item transformer meter to the zero line: 1. The rated voltage of the watt-hour meter should be consistent with the power supply voltage, and the rated current should be 5A.

2. The secondary wire should use insulated copper wire, and its cross-section: the voltage circuit should not be less than mm2; The current circuit should not be less than the three-phase three-wire connection method through the current transformer: 146 is connected in parallel to the three-phase power line, 23, 78, respectively, and 147 is connected to the K1K2 end of the two-phase current transformer, and the K2 end of the two transformers is connected and then grounded.

4. The accuracy of the current transformer should not be lower than the grade. The polarity of the current transformer should be correct.

There are two reasons why the meter of the transformer is wired correctly and does not go:

1. The meter wiring of the transformer is correct, and if it does not go, it may be that the mechanical energy meter turntable is rotating, the pulse light of the electronic meter is flashing, the reading does not go out, the integrator is faulty, and the integrator needs to be replaced.

2. The turntable of the loaded mechanical electric energy meter does not rotate, and the pulse light of the electronic meter does not flash, which may lose voltage or the voltage coil burns out the open circuit or the voltage sampling board fails, and the voltage coil or voltage sampling board needs to be replaced.

Analysis of the reasons why the meter does not go;

1.The mechanical energy meter turntable is rotating, the electronic meter pulse light has a flash, the reading does not go out of words, and the integrator is faulty, 2The turntable of the loaded mechanical electric energy meter does not rotate, and the pulse light of the electronic meter does not flash, and the voltage coil may be lost or the voltage coil burns out the open circuit or the voltage sampling board fails, 3Two elements one of the reverse polarity, 4Three-element polarity, one positive, one negative and one loss of voltage, 5There was no electricity at all.

Is the watt-hour meter connected to a voltage line?

Summary. <>

Hello, dear, very happy to you your question, through the transformer meter and not through the transformer meter is not the same meter, to help you find out, no. There is a difference between a phase power meter with a transformer and a non-transformer, and a meter without a transformer is a pass-through meter. The electric power is 100A, and the meters with transformers are 3 three-phase four-wire AC active energy meters, 3 means that in the case, meet the requirements of the national standard for error, (6) means that it can be used for 4 times the basic range of the condition, that is, it can be used for 3 6A occasions.

A meter that passes through a transformer and a meter that does not pass through a transformer is not the same meter.

Pro, when choosing a watt-hour meter, pay attention to its rated current and rated voltage. The rated current of the watt-hour meter should be greater than or equal to the calculated current of the line, otherwise the accuracy will be lower and the life will be shortened. The watt-hour meter is also not allowed to be used in circuits where the load is often lower than the rated value of 5 because it does not properly measure the amount of energy consumed.
