But the features of the inductive current limiter
, using an additional superconducting screen, have not been investigated.

It can be seen that the circuit of the active current limiter
holds the transistor in the linear region for the time necessary so that the parasitic capacitance is discharged; limiting the current through it to the value defined in (9), in this case a value very close to 8 A.

Superconducting fault current limiters
can limit short-circuit currents in power transmission and distribution grids very quickly, effectively, automatically and, thus, with a high degree of intrinsic safety, making reliable grid operation possible even under difficult conditions.

Southern California Edison has a separate project to test another fault current limiter
, designed by American Superconductor.
In one of these, SC Power Systems will develop a 138-kV saturable reactor type of fault current limiter
Holtkoetter is also developing a proprietary electronic current limiter
for its torchieres, which it will show at the June Dallas Market.
A higher wattage bulb does draw more current but in this case the bulb is being used as a current limiter
in the circuit.
