In other places I have read that to sense currents above 150 A AC it is not recommendable using current transducers or shunts because of power dissipation. Also there are good TC brands as VACUUMSCHMELZE which provides high quality current sensing up to 2000 A AC. I want to start designing a energy metering in the range of 1000A AC, but the ADE7978 seems not suitable due to the current values. Also, this chip does measure the Total Reactive Power and Energy. The ADE7880 seems better choice, but it only measures the fundamental for Total Reactive Power and Energy.
If anyone can help me on this, I really appreciate that.
