What are the new functions of smart meters compared with traditional meters?

It has the function of measuring positive and negative active energy, can store its data, and can set the combined active power accordingly;

The active electric energy accumulates and stores the total, peak, average and valley electric energy respectively according to the corresponding time period;

It has perfect multi-rate settlement and billing function, and can set two groups of time periods, and each group of time periods can set four rates;

Support to modify the tariff and timetable through infrared and RS485 communication interfaces;

It can store one-way or two-way total electric energy and electric energy data of each rate on 12 settlement days. When the watt-hour meter is out of power, all data related to settlement shall be kept for at least 10 years, and other data shall be kept for at least 3 years.

The external plug-and-play carrier communication module is adopted, and the carrier communication interface has a fault protection circuit, which works independently with the metering part;

Power line carrier communication module can realize remote real-time meter reading, periodic reading of meter reading data and remote on-off control;
