As OSHA Professor stated, these voltages are anything but phantom when it comes to medium and high voltage. I used to due regular PM and repair work on some large xfmrs, 26.4KV/600V feeding large DC drives(2 x 2500 hp). Full HV PPE is required to ground the primary side conductors even after LOTO of the line disconnect. You connect the ground clamp first, then swing the line clamp at the feeder connection and ZAP! There is enough stored energy due to the capacitance in the cable and xfmr to kill you. It's sobering to see a cable (open on both ends) crack an arc.
