Medium Voltage, Voltage Drop Calculator

[ALTupa]

There are many good voltage drop calculators for 120 volt to 480 volt. Mike Holt has given us two from his contributors.
I need to calculate the voltage drop of a cable for a 4160 volt motor. I can get the cable size from NEC table, but I cannot find anyone so far who has a method for medium voltage drop. Wire manufacturers and motor manufactures have not been able to give me any information (from the WEB and phone calls)?
Does anyone have a calculation method?

Some engineers prefer their own spreadsheets. Post the details and let us armchair generals debate the results.

the basic method is the same Vdrop = I x Z
but you need the ckt pf and conductor Z = R +jX
this is dependent on the cable type and installation configuration
