Would this minimize corona losses, its cables wrapped around the main line, with voltages dividers

In your drawing, it's unclear where is the reference node for the stated potential-difference values.
Can you show a circuit including a voltage source with two terminals?

As for voltage dividers, the only labeled nodes are "68 kV", "34 kV", and "100 kV" in that order along a pair of 1M resistors. What are the bias current directions? Is there more than one unseen voltage source?

What are you going to use for a 68 kV resistor?

A water/salt resistor, copper sulphate or iron sulphate, in a PVC pipe, it probable won't be accurate

Note that the current through the 1 Mohm resistors would be 33 mA. The power supply would have to provide 3.3 kW just for this...

Yeah the resistors values wasn't worked out fully, but would the idea of having multiable wires wrapped around each other with low voltages further out work.

Thanks

Instadeath on contact comes to mind, as well as burns, fire, and electrocution. Not to mention ozone poisoning from the discharges and all. Completely safe, really.

And that's why we love it :D

You never stated the energy levels of those high voltages. I don't know what
your jurisdiction is, but there are laws about where and how high voltage gear
is installed, and who may work on it.

The term 'qualified worker' is defined as one skilled in and trained in the hazards
of an occupation.

See if this document is on line for making and refilling high voltage resistors.
