We have single phase (120v)branch outlet from a 3 ph. Y sub-panel. There is only one outlet on the circuit. The panel itself serves many electronic devices. We measure between 1 to 2 volts between the neutral and the IG on the branch ckt. Is there a "plain english" explanation of how this voltage is caused and is an isolation xfmr at the point of use the best fix?
The neutral to ground voltage is creating problems with an electronic scanner.
