✦ Synopsis

A transient induction heating technique is used to study the stability measurement of three-component, Cu/Cu-Ni/Nb-Ti superconducting wires. The wires are available for developing a low and quick response excitation field winding for superconducting generators. Quench energy measurements on the wires using the induction heating technique are useful for determining stability against short transient disturbances. The measurements suggest that conductors for field excitation windings should have quench energy as high as or higher than 104 J m-3; a value which is sensitive to current density, the copper to superconductor ratio and the heat transfer coefficient. These results are used to discuss recovery from a strong disturbance and quench propagation.
