Three-Phase Four-Wire Electronic Prepaid Electric Energy Meter Function Introduction

1. Prepaid function: The three billing modes are single rate, stepped rate and multi-rate.

2. Anti-stealing function: It can prevent common electricity stealing methods, such as magnetic electricity stealing.

3. Overdraft consumption function: the meter can be programmed to set the user's overdraft amount.

4. Electric energy measurement and electric parameter measurement functions: active power, reactive power measurement, power factor, frequency and other parameter measurement functions.

5. Load control function: the electric meter can be programmed to set the user's electricity load threshold, and overload alarm tripping can be set.

6. Event detection and recording function: able to detect and record events such as cover opening and overloading.

7. Automatic protection function: self-check function of memory, relay and other faults, alarm when abnormal.

8. Pre-alarm function: alarm when the remaining amount is lower than the threshold.

9. Measurement functions of each phase power factor, line frequency, phase angle, and voltage angle.

10. Provide phase failure indication, and voltage/current phase sequence detection functions.

11. Remote communication function: support GPRS, PLC, NB, RF, and other communication modules to choose freely.
