Impedance data for 400-cycle aircraft distribution systems

This paper presents impedance data which the authors have compiled for use in designing and testing aircraft electric systems employing 3-phase 400-cycle auxiliary power. Tabulated herein are impedance data for a number of typical configurations employing multiple-wire feeders in 0.5-inch flat spacing and laced 3-phase groups. Sufficient background material and procedure are given to enable the reader to calculate additional data for configurations not actually tabulated.
