Product Introduction
Three-phase Smart Electric Meter Feature

 

Three-phase smart electric meters are core metering devices for industrial, commercial, and high-voltage electricity usage scenarios. Adopting high-precision sensing and digital technologies, they accurately measure voltage, current, power, and total electricity consumption in three-phase circuits. Supporting remote meter reading, real-time data transmission, and abnormal electricity usage monitoring, they feature anti-theft and overload protection functions. These meters can be connected to smart grids for electricity data analysis, facilitating efficient electricity management, meeting energy conservation, emission reduction, and precise billing needs. They are suitable for high-power electricity scenarios such as factories, shopping malls, and office buildings.
