Multi-user smart meters are meters used to measure electrical energy. They can simultaneously detect 36 households (single-phase), 12 households (three-phase), and any combination of single-phase and three-phase households below 36. They are commonly known as multi-user meters.
Such a simple combination is bulky, unattractive and uneconomical. It is necessary to design a centralized, multi-user, all-electric energy meter with small size, complete functions and economy. This centralized table can be used in the same unit or even a building, but it is not a simple combination of multiple single tables.
Multi-user smart meters how to see the correct degree. Peak, valley, and flat are the data measured by the energy meter during these three periods. The sum of the three is your power consumption. When the meter displays "Total", the displayed data is the power of your meter. Generally, the data displayed by your meter is the largest. Of course, multi-function electronic meters or smart energy meters will also display other data, such as forward and reverse reactive power, maximum demand, time, meter bar code number, etc., you must read the display above the display ** Chinese character.
As a multi-user smart meter as an instrument, it must be accurate in measurement. This requires a rigorous test at the factory. Today we will take you to see how it is detected.
The electricity meters installed in each household must be tested after being rigorously tested. Especially, the smart meters used today are not only free of mechanical wear compared with the mechanical meters in the past, and the measurement is more accurate. In order to pass the acceptance check, we have formulated a detailed multi-user smart meter acceptance procedure. From the entire process of "production-factory-test-installation-use-disposal" of the meter, the staff will not disassemble the meter, but only pass Various instruments test their performance. If the meter needs to be repaired, it is directly returned to the manufacturer for repair. If the public thinks that the meter is inaccurate, they can apply for a calibration.
