A new classification of superconducting current fault limitier (SCFL) is described which is a non-quenching, variable-inductance-mode "VIM" current limiter with characteristics matched to utility distribution line parameters. A major application of this device is for replacement of fixed-inductance air-core reactors used in impedance and short-circuit levles from sub-transmission to distribution.The secondary application to distribution. The secondary application transformers in the 5 - 40 MVA range, as a replacement for current limiting fuses and air-blast circuit breakers. The SCFL devices have the unique characteristic of producing minimal or no transient recovery voltage (TRV) as is typical of conventional interruption technologies.
