Abstract
The measurements, data reduction, and analysis contained herein are for the most part preliminary. The instrumentation system for dynamic measurements was not completed and so the measurements taken were in the static mode and a limited amount of instruments was used. Most of these preliminary measurements were made to characterize the losses in the roadway and the pickup of the dynamic RPEV system. By analysis of power, voltage, current and impedance-bridge measurements (at 100 Hz and 1000 Hz), the equivalent series resistance (ESR) and equivalent parallel resistance (EPR) of the roadway and pickup inductances and capacitances were derived. Separation of the inductive and capacitive losses was difficult because of the large ratio of stored energy to power loss, that is, the Q of each of these system elements, and the separation was accomplished by modeling the system losses and making a least-squares fit to the model with the test data. The bridge data was used primarily for capacitance and inductance values and the ESR or EPR data were not analyzed.
