The Wiki article mentions line losses in a transmission line. Losses in watts = I² x R. For a fixed length of line the
resistance R is fixed. For a fixed resistance, the heat losses dissipated is = V² x R. Therefore is you are using selected conductor size and a given acceptable loss, the...

It sounds like you are caught up in that old example the flow of
electrical current is like water flowing through a hose. Nothing
could be further from the truth. If you take a simple circuit like
a lamp and connect the two wires from the lamp to 120 volts the lamp
lights. At the time...
You obviously have other paths being used. Does you local code allow
the water pipes to be used in the grounding system?
100 amps is a lot on a single phase line. I am surprised that you
are not receiving electrical shocking complaints.
Quote waross "So when a motor is operated at the star voltage rather than the delta voltage the life expectancy is 1/700 or 0.14%."
I don't follow your math.. I would say the operation at the voltage stated would reduce the life time hours = 700/expected lifetime hrs.
I am not familiar with...
%Z is not the transformer impedance but you can obtain it form the transformer information. The links below
explain it in detail.

Have you calculated the amperage at 66 kv and 220 kv. Looks like you need a generation plant in the back yard. At 220 kv calculate the VD at max load. Then decide what you need to do.
Are you speaking commercial/industrial design or something like utility power distribution? They are different. I google your question and found the following:
