    Ok, I think you front the electrical field coupling phenomenon in step down switchgear. Some high voltage indicator voltage with capacitors can provide that mentioned coupling. Indeed you front the feed-back voltage on disconnected phase via connected phase and load indicator capacitors as shown below. For override that induced capacitive voltage you can remove relevant indicator in switchboard panel.
