MIL-HDBK-1004/5
If the series compensation is changed form 12 to 14 percent, the
airplane interface connector steady state voltage (100-ampere, 0.8-power-
factor load) will increase by 0.0497 - 0.0428 = 0.0069 per unit (Table A-5)
where unit voltage is 118 volt1-n. This increase in voltage at the airplane
service interface connector is:
(0.0069) (118 volts1-n) = 0.814 volts1-n
The results are not linear. An increase from 12 to 20 percent will
increase the aircraft interface connector voltage by 2.6 volts1-n for a given
cable length (for a 100-ampere, 0.8-power-factor load).
The resistance of the cables and transformers has a more pronounced
effect on voltage drop at high series compensation where the reactive
impedance cancels out.
