I take it calculations are Calculations HV or LV .
Calculators on line seem to work for both HV & Medium voltage.
Any one know any different.Or have link to HV Calculators???
I know terms are 90c not 75c And cable amperage of cable different .
Thank you .

Example below
1 conductors per phase utilizing a #3/0 Copper conductor will limit the voltage drop to 1.76% or less when supplying 200.0 amps for 8000 feet on a 13800 volt system.
For Engineering Information Only:
200.0 Amps Rated ampacity of selected conductor
0.077 Ohms Resistance (Ohms per 1000 feet)
0.042 Ohms Reactance (Ohms per 1000 feet)
345.0 volts maximum allowable voltage drop at 2.5%
242.798. Actual voltage drop loss at 1.76% for the circuit
0.9 Power Factor
