How to read the degree of the electronic energy meter and how to read the degree of the electronic energy meter? In addition to the basic electricity metering function of traditional electric energy meters, in order to adapt to the use of smart grids and new energy, it also has two-way multi-rate metering functions, user-side control functions, two-way data communication functions with multiple data transmission modes, Intelligent functions such as anti-theft function. Smart meters represent the future development direction of intelligent terminals for end-users of energy-saving smart grids, but they are not yet popularized. There are still many people who don’t know how to look at smart meters, but it doesn’t matter. Today I will teach you how to look at smart meters. Hope it can help friends who have this need!
What is a smart meter
A 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 metering function of the basic electricity consumption of the meter, in order to adapt to the use of smart grids and new energy, it also has a two-way multi-rate metering function, a user-end control function, a two-way data communication function with multiple data transmission modes, and an anti-theft function. Smart meters represent the future development direction of intelligent terminals for end-users of energy-saving smart grids.
How to read degrees on an electronic meter
First of all, there are four values on the 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, some smart meters may only have two or three items, but this does not affect the way we look at the meters. These four values actually refer to the tariff period. The most advanced because it represents the highest electricity price, that is to say, the electricity consumption rate during peak hours is the highest, and so on. This 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.
How to read the degree of electronic energy meter
The first type: general straight-type single-phase electric meter and three-phase electric meter can directly read the number Subtract the last reading to get 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: a three-phase meter connected by a current transformer connection, the meter has 10 wires, and the current ratio of the connected current transformer should be observed, and the nameplate of the current transformer should be observed. There is, it is marked by a number ratio of 5, such as 100/5 150/5, etc. The number read on the meter multiplied by the current ratio is the measured amount of electricity, plus the change loss and line loss to be precise.
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.
