The magnetic fields that the CT leads create would have an effect on the voltage and Vref conductors. How much depends on the orientation of each CT lead with respect to the voltage conductors.
To test how much the CT leads are affecting the voltage leads is to run the currents and measure the voltage with respect to ground on the Vref conductor (assuming that Vref is also in the conduit). This will give an idea of how badly the CT leads are affecting the conductors.
