The impedance of feeders used with variable-speed and constant-frequency (VSCF) generating systems in airplanes is severely affected by the non-sinusoidal generator current and the airplane frame. The above effect was experimentally investigated for frequencies from 1500 to 3500 cps. Data obtained are...
