    unbalanced current and Zero sequance component

    if there are 3 line (3 phase power system)passing through a ring transformer (core balanced CT) and feeding unbalanced delta load. Does the core balanced CT get an output (secondary winding) related to this imbalanced current?. or it will only get an output in the case of earth leakage?.
