Need example to connect current transformer to ADE7933

Is there an example of how to connect the ADE7933 with current transformers?

Thank you

    thanks for your reply

    Because of the application we must use a CT

    It is only a standard life-neutral and ground configuration (110V - 220V)

    Adding a shunt current sensor will be more expensive and complicated

    It will require some mechanical changes which are ussually very expensive

    We already have a current trasnformer version with several customers

    I can scale the CT output to match the ADE7933 input

    I understand the redundancy of the isolation of both devices but it is simpler to use a current transformer

    This device together with the ADE7978 will simplify our firmware implementation.

    any notes on current transformer or any other device that you could suggest will be appreciated

    Thank you
