A smart meter designed for power monitoring needs of power systems, industrial and mining operations, etc. As an intelligent and digital front-end collection element, it is used in various control systems and energy management.
Disadvantages of traditional instruments:
In the original power system, a variety of mechanical instruments (such as watt-hour meters, ammeters, voltmeters, etc.) are often installed in high- and low-voltage power distribution cabinets to monitor the power system. It is time to go to all instrument points for manual meter reading to provide a data basis for future data analysis and processing. In this working mode, due to the installation of a large number of complicated instruments, the production operation cost and labor cost are greatly increased, and the work efficiency is low, and it is prone to record errors.
Advantages:
Because not only can be used in one table, but also can realize the functions of programming settings and data collection of the instrument by the host computer or handheld programmer through its communication interface, the use of multi-function network power meters can be greatly reduced Labor costs, reduce operating costs, and can greatly improve work efficiency. At the same time, the meter has perfect communication networking function, which is very suitable for real-time power monitoring system. It can be used locally or form a high-performance telemetry remote control network through the field bus.
