Analysis of the Reasons for Reverse Electricity Quantity Caused by Abnormal Voltage of an Intelligent Energy Meter

Combining with the 10 kV high supply and high meter users who use V/V-12 wiring voltage transformers, the measurement abnormality caused by the voltage circuit fault of the intelligent energy meter during operation is analyzed. The change law of the collected system curve data before and after the voltage circuit fault is analyzed, and the amount of electricity to be replenished during the voltage circuit fault is calculated. Detailed preventive measures are proposed.
