Functions and Operating Principles of Electronic Electricity Meters
1. What is an electronic electricity meter?
Electronic electricity meters utilize large-scale integrated circuits (LICIs) and digital sampling and processing technology. Their design incorporates various anti-interference technologies. They are used for time-sharing measurement of AC active energy with a rated frequency of 50 Hz, helping to better balance grid loads.
2. What is the operating principle of an electronic electricity meter?
An electricity meter consists of two main components: an energy metering unit and a microprocessor control unit. The metering unit uses a large-scale, dedicated integrated circuit (ASIC) to generate a pulse train representing power consumption, which is then sent to the microprocessor for energy measurement. After receiving the pulse signal, the microprocessor accumulates the number of input pulses and accurately measures the electrical energy based on the pulse constant. Data is then transmitted through various interfaces to implement various control functions.
III. What are the functions of an electronic energy meter?
Metering: Accurately measures forward/reverse active and reactive energy, adapting to diverse electricity demands.
Time-of-use billing: Divides into multiple tariff periods for reasonable billing.
Data management: Stores historical data, including daily/monthly freezes, and supports multiple freeze types to facilitate analysis and management.
Real-time monitoring: Measure electrical parameters such as voltage and current in real time, allowing users to easily understand electricity usage and troubleshoot anomalies.
Communication meter reading: Supports multiple communication methods, enabling remote meter reading, data upload, and parameter settings.
Prepayment and fee control: Prepayment prevents arrears and allows for some remote power control.
Events and alarms: Record anomalies such as voltage loss and overload, and generate alarms to notify users and the power company.
Security: Encryption and anti-theft design ensure data security and prevent tampering and theft.
