[How to read the electricity meter] How to read the electricity meter reading method
How does the energy meter look?
The smart meter represents the future development direction of the intelligent terminal for the end user of the energy-saving smart grid, but it is not yet popular, and there are Many people don’t know how a smart meter looks, and I will answer it for you below.
The smart meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic electricity consumption measurement function of the traditional electric energy meter, the smart meter is suitable for the smart grid and new energy. It also has intelligent functions such as two-way multi-rate metering function, user-end control function, two-way data communication function of multiple data transmission modes, and anti-theft function.
Meter reading method
I. How to see the smart meter

First of all, there are four values on the electric meter in my house. These four friends who have read the manual may know that they are sharp, peak, flat, and valley. According to the Internet, there are some smart meters in some places. There are only two or three items, but this does not affect us looking at the electricity meter. These four values actually refer to the tariff period. Generally, the peak is at the front because it represents the highest electricity price, that is to say, the peak period The electricity rates are the highest, and so on, which is actually designed by the power department to encourage us to use electricity during off-peak hours.
The electricity bill of each household is calculated according to the jumped metering of these four time periods, which means that in the end your total electricity consumption is calculated according to the sum of these four values. So many people complain about the sudden increase in electricity bills, mainly because of excessive electricity consumption during peak periods. This is your electricity consumption, so how do you see how much electricity is left?
There is a button on the smart meter, this button controls 28 functions of the meter, but you don’t need to press it a lot, you only need to press 2~5 times each time (this depends on different regions), you can see the remaining electricity bill or Battery remaining.
Second, what about other electric meters
The first type: general straight-type single-phase electric meters and three-phase electric meters can directly read digital minus The last reading is the power at this stage. The incoming wire of the straight-type meter is thicker, and it is carefully observed that it is not connected through the transformer.
The second type: The three-phase electric meter is connected by the current transformer connection method. The connection of the electric meter has 10 wires. The current of the connected current transformer should be observed. Ratio, there are on the nameplate of the current transformer, which are marked with a number ratio of 5, such as 100/5150/5, etc., the number read on the meter multiplied by the current ratio is the measured amount of electricity, and the accuracy must be added to the variable. loss and line loss.
The third type: Single-phase electricity meter measures the electricity of three-phase electricity. The meter should read the number of the meter and multiply it by the current multiple of the transformer and then multiply it by 3.
