    We are now doing energy metering using the ADE7878. There is a problem with current measurement.
    

    If only one IA is measured by connecting the CT sensor, the correct value is measured.
    

    However, when two CTs are connected, such as IA and IB or IA and IC, the value is lowered.
    

    Do you have any way to solve this problem?
    

    please answer about my question.
