Learn About the Classification and Functions of Smart Energy Meters
Classification
It is composed of a measuring unit, a data processing unit, a communication unit, etc. It is an electric energy meter with functions such as electric energy measurement, data processing, real-time monitoring, automatic control, and information interaction.
Smart energy meters can be divided into single-phase meters and three-phase meters according to user types. According to different payment methods, it can be divided into local table and remote table.
Single Phase Ammeter
A single-phase meter, as the name suggests, is an electric energy meter used by ordinary users to measure 220V electricity. Three-phase meter, that is, the electric energy meter used for measuring 380V electricity used in industry.
The local meter, that is, the electric energy meter that can be paid by IC card on the user side. Remote tables, such tables are generally not installed in the user scope.
Function
The user holds the IC card to the power supply department to pay for electricity purchase, and the power supply department uses the electricity sales management machine to write the purchased electricity into the IC card. Then the power is available, and the card can be removed after power is supplied. When the remaining power in the watch is equal to the alarm power, the power off alarm (or buzzer alarm) will be triggered. At this time, the user can swipe the card in the induction area to return to normal. At this time, the user can restore the power supply by swiping the card in the induction area; when the remaining power is zero, the power is automatically turned off, and the user must pay for the electricity with the card again, and then the electricity can be restored. Effectively solve the problem of difficult door-to-door meter reading and electricity bill collection. At the same time, the user's electricity purchase information is managed by computer, which is convenient for inquiry, statistics, charging and printing bills. It has the advantages of dual display, accurate measurement, stable precision, security and confidentiality, complete functions, low power consumption, and simple and convenient operation.
