Zusammenfassung:	Testing, results and analysis of a Bi-2223 model superconducting generator coil produced under the DOE Superconductivity Partnership Initiative are presented. The test arrangement enables coil energization with DC and transient currents over a range of operating temperatures to explore coil performance under conditions analogous to those that would be experienced by a superconducting generator field coil. Analytic calculations of coil AC and ohmic losses and temperature rise compare well with experimental measurements. Good performance is predicted for a typical three-phase fault condition. Coil steady-state and transient performance can be predicted with confidence for full scale superconductor application.
