It is depend on type of scheme, in protection , if three phase ckt then reversal of 1 CT polarity relay will (if set value Reach), reversal of all three phases will not effect for normal protection (except to directional protection). In case of metering Ameter will not effect, but energy meter will not work,if single CT reverse in case of three phase, mode (import/export) will change.
