Electricity is one of the greatest inventions of the 20th century. It not only provides light for our lives, but also provides a certain carrier for many industries, especially in today's society. Electricity is ubiquitous, and its application fields are also very extensive, whether in daily life or in the field of technology.
The network needs electricity, households need electricity, and industries need electricity. Electricity has been distributed in every corner of our daily lives, indicating that electricity plays a crucial role in our lives. Electricity is not free and needs to be purchased. Whether it is household electricity or industrial electricity, there are electricity meters in the parts where electricity is used, which is the main basis for recording electricity usage, To purchase electricity, it is necessary to read the numbers on the meter clearly, and many people cannot understand the numbers on the meter. So, how to read the numbers on the meter?
In fact, electricity meters can be divided into many different types, including the oldest and the latest, and the displayed numbers are also different. So, how should different electricity meters look at their numbers? The editor has organized several forms of electricity meters as follows:
1. A typical electricity meter can directly read the total usage so far, and then subtract the previous month's usage to obtain the current month's usage.
2. The smart meter has only one LCD screen. If it is a single phase, it will directly display the total power and remaining power, which can be read directly.
3. If it is an IC card meter and only the LED display is a single graphics card meter, there will be a small red dot on the meter. Jumping the red dot to the total usage is the total usage, and jumping to the remaining is the surplus. Dual graphics card watch, can be read above or below.
4. Direct reading of three-phase prepaid electricity meters with direct input.
5. Multiply the reading of the mutual inductance meter by the transformer magnification.
In summary, the reading situation of several types of electricity meters compiled by the editor is basically the same, and it basically includes all forms of electricity meters. The reading situation of these forms of electricity meters is the same. For those who are not sure how to read the meters, they should remember the reading methods of these different phenotypes. These methods are actually relatively simple and can clearly read the meters, At least it is possible to have a clear understanding of one's electricity usage, and I hope it will be helpful to everyone.
