Scope of use of primary and secondary electric meters
The first-class ammeter is a kind of ammeter with single-phase measurement ability. Widely used in low-voltage power grid, used for electricity consumption measurement in homes, offices, enterprises and other places.
Secondary ammeter is a kind of ammeter with three-phase measurement capability, which is often used in industry, commerce and public utilities for electric energy measurement and management.
Second, the functional differences between the primary table and the secondary table
Class I meters usually have only a single metering function, which records the total electricity and peak and valley electricity.
The secondary meter can measure the total electricity, peak-valley electricity and power factor, so as to better realize the management and control of electricity consumption.
Of course, this is not all the functions of the secondary instrument. In contrast, it can also carry out more detailed electricity consumption statistics, such as load deviation, voltage margin and other management control indicators, which is very important for some fields with high requirements for accurate calculation and management of electricity consumption.
Thirdly, the influence of the difference between the first-class meter and the second-class meter on power management.
For power users and power companies, power resource management is a necessary and complicated work. Therefore, the problem of power management and control can be effectively solved by collecting, sorting, analyzing and managing the data through the corresponding electric meters. The difference between primary table and secondary table also means that there are huge differences in data processing and management.
Because of the difference in measurement interval and accuracy between primary meter and secondary meter, secondary meter can provide more accurate data in power management, so that power companies can better control power consumption and power quality and realize sustainable development.
Generally speaking, there are some differences between the first-class meter and the second-class meter in measurement accuracy and function. This is very important in the field of power management, because they can provide more accurate data of power consumption and better realize power quality control and sustainable development.
