Features and Applications of Multi Function Electrical Energy Meters

Multi function electrical energy meters are advanced instruments used for measuring electrical energy in high and low voltage power grids. In addition to measuring active and reactive energy, they offer time-based metering and demand measurement, along with data display, storage, and output functionalities.

Features of Multi Function Electrical Energy Meters

Measurement Function: Multi function electrical energy meters can measure forward and reverse active energy as well as four-quadrant reactive energy. They support time-based metering, allowing accumulation and storage of total, peak, high, medium, and low energy consumption for both active and reactive energy.
Parameter Monitoring: These meters can measure, record, and display key operational parameters such as total and phase-specific voltage, current, power, and power factor with minimal error. If any parameter exceeds or falls below a preset threshold, an event record is generated.
Display Function: Equipped with a large LCD screen, these meters support both automatic cycle display and manual button-activated display. In addition to showing routine energy data, they also display error symbols and issue alerts when abnormalities occur.
Communication Capabilities: Multi function electrical energy meters come with various communication interfaces, such as RS-485 and infrared communication ports. They can also integrate NB-IoT, 4G wireless, or power line carrier communication modules, ensuring stable and independent data transmission.
Load Curve Recording: These meters can log data at preset intervals, capturing voltage, current, frequency, active/reactive power, power factor, and total active/reactive energy in various combinations for detailed analysis.
Event Logging: The meters maintain detailed fault event records, supporting remote fault diagnosis. Logs include reset counts, time corrections, loss of current or voltage, phase loss, cover opening, power outages, power anomalies, and breaker operations.
Power-Outage Data Retrieval: Even during a power outage, users can retrieve energy data using button activation or infrared communication.
Prepaid Control Function: These meters can receive commands from a backend system to execute power disconnection or reconnection. Commands undergo strict password verification and security authentication to ensure safe power management.
