    I agree - the yanks in effect have a CNE/PEN on their HV system - and tend to use a common HV/LV earthing system even for small transformers with high local electrode resistances - so I reckon what he's seeing is diverted N current from the HV system. 2nd guess would be some capacitive coupling between the HV and LV windings of the transformer.
