Nothing unusual about that outcome. The CT's are simply responding to the instantaneous values of the current. If they are identical in all other respects but physically transposed by 180° on the conductor then their individual electrical output phase relationships will also be 'transposed' by 180°.The scoped output waveforms from the CTs shows two AC waveforms; by turning one CT 180 degrees to the other, the waveform moves 180 degrees out of phase with the other.
Are you trying to balance the loads on each side of the CT, or are you looking for an instantaneous power "snapshot" from each side at the same moment?Thanks for the advice. The measurement of the current is not a problem. The direction that the power is flowing in the conductor is the problem I am trying to determine. I have experimented with a pair of current clamps applied to a single conductor. The scoped output waveforms from the CTs shows two AC waveforms; by turning one CT 180 degrees to the other, the waveform moves 180 degrees out of phase with the other. Can anyone suggest a typical circuit that would identify power flow in a conductor from these scope traces?
