Hello I want to use ADE7753 but I want to know what is the active and reactive energy accuracy of this device, or if any know other better device for a energy meter project.
there are multiple things that affect the accuracy including the external current sensor (Rogowski or shunt) and the calibration algorithms.
The ADE7753 exceeds the specification set by the IEC standards with less than 0.1% error in active energy measurement over a dynamic range of 1000 to 1 at 25°C
High accuracy; supports IEC 60687/61036/61268 and IEC 62053-21/62053-22/62053-23
