The minimum wattage of a 100 amp meter does not go 5

Thank you, the neighbors you said don't live in the same unit, if they are not in the same house, it may be that the electricity meter is different. The old-fashioned meter, it's turning, you don't use electricity, it doesn't go. It's like the odometer on the car, if you don't drive the car, it won't show the mileage.

So I don't feel like it's going fast. The new type of meter is a smart meter, and it will go when the indicator light is on, not to mention the charging of mobile phones and routers. It's a bit like a taxi meter, and the car will go out of the meter when it stops in front of a red light.

I am now more than one every month, the refrigerator is all day, the TV is at night, the range hood is twice, the wall-hung stove is three hours, the lighting is dozens of watts at night, the others are charging, and other electrical appliances are occasionally useful for many days. It feels like your home is a bit much, it should be about four degrees a day, about 120 degrees a month. If the meter is in the hallway, you can look at the neighbor's meter and see how many degrees they use in a day, then a week or a month.

Choose the same house type, and the family members are almost the same family to see. It is to write down the number of the meter, and then subtract it is the electricity number, which is a way. Because the electricity consumption at home is not easy to calculate, especially the power consumption of chargers, TVs, and computers in the standby state, if it is not outrageous, you can't calculate.

So, I just feel like my neighbors, and it's not comparable to the old meter. There is a neighbor upstairs who does not live, just turn on a heater, several degrees a day, like this can suspect the meter problem, you have to find it.

If this is the minimum 30 watts, he won't leave, so you have to look carefully.

100A meter, its minimum they still have 700,000, if we don't go, I think it must be a product quality problem, or you can check it.

The average meter does not go how many watts it is, it should be 15 watts.

Hello, 50,000 watts is enough for a 100 amp meter.

If the maximum power is 100A, a meter is not enough.

If a 220V single-phase power supply is used, the meter with rigid current i=p u=50000w 220v= is not enough.

If it is a three-phase 380V power supply, a 100A three-phase meter is enough.

If a load of 50,000 watts is used at the same time, it is not enough. This mainly depends on whether the rated current of the device you are starting at the same time exceeds 100A, if it exceeds 100A, it is definitely not possible. All of them are three-phase 400V loads, and if these devices are used at the same time, this current is a bit small; If there is a three-phase 400V load and a two-phase 220V load, and these loads need to be used at the same time, this energy meter must be small.

First, the selection of electric energy meter.

1. The rated capacity of the electric energy meter.

It should be selected according to the user's load, and the upper limit of the general load current shall not exceed the rated current of the electric energy meter, and the lower limit shall not be lower than the load current specified within the allowable error range of the electric energy meter.

2. The principle of selecting electric energy meters.

The electric load should be used within 20%-120% of the rated current of the electric energy meter, and the appropriate electric energy meter must be selected according to the load current and voltage value, so that the rated voltage and rated current of the electric energy meter are equal to or greater than the voltage and current of the load.

3. To meet the requirements of accuracy.

4. According to the type of load, determine the type of selection.

Energy meters.

Second, the working process of the electric energy meter.

When the electric energy meter is connected to the circuit under test, there is alternating current flowing in the current coil and the voltage coil, and these two alternating currents produce alternating magnetic flux in their iron cores respectively; The alternating magnetic flux passes through the aluminum disc and induces eddy currents in the aluminum disk; The eddy current, in turn, is subjected to force in the magnetic field, which causes the aluminum disc to obtain torque (active torque) and rotate. The greater the power consumed by the load, the greater the current through the current coil, and the greater the eddy current induced in the aluminum disc, the greater the torque that makes the aluminum disc rotate. That is, the magnitude of the torque is proportional to the power consumed by the load.

The higher the power, the greater the torque, and the faster the aluminum disc will rotate. When the aluminum disc rotates, it is affected by the braking torque generated by the permanent magnet, and the braking torque is opposite to the direction of the active torque; The size of the braking torque is directly proportional to the speed of the aluminum disc, and the faster the aluminum disc rotates, the greater the braking torque. When the active torque and the braking torque reach a temporary balance, the aluminum disc will rotate at a constant speed.

The electrical energy consumed by the load is directly proportional to the number of revolutions of the aluminum disc. When the aluminum disc rotates, the counter is driven to indicate the electrical energy consumed. This is the simple process of working with an energy meter.

Hello dear, the reason is that there are actually two metering devices in the meter: the electronic part and the mechanical part. Because the structure of the mechanical part has been verified for many years, and it will be strictly calibrated before leaving the factory, there will generally be no errors, so it is stipulated that the calculation of electricity is actually based on the mechanical part.

However, the two systems operate at the same time, and the electronic part is not as accurate as the mechanical part, so the actual electricity measurement of the two meters is actually different, so the display is not the same as the ......The normal power supply communication, power purchase, and power outage are stupid and the electronic part shall prevail. So this creates the so-called electromechanical mismatch. At this time, the meter will generally be removed and calibrated or replaced, and then the difference will be calculated according to the measurement results of the mechanical part and the actual payment amount.
