isolating medium voltage cable

[gaven]

I am in the process of replacing a 5kV shielded cable and writing the procedure to isolate the cable. Will a voltage detector sense the voltage of an energized shielded cable?

Not through the shield. If there is no other way to prove you have the correct cable, sometimes a "penetrating ground clamp" is used.

The only way to ensure a MV circuit is dead is by effectively earthing the conductors at both ends, many switches have this facility built in.

I use hot sticks to prove dead before earthing the conductors to be worked on.

good deal. Thanks a lot for the info.
