## Voltage Drop HV 13800 volts - 06/27/18 01:02 PM

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
