A fault current limiter in toroidal form to maximise effective Jc

The performance and characteristics of a new form of inductively coupled fault current limiter (FCL) are described. It has a toroidal geometry and the prototype windings comprise 20 series connected primary coils interleaved with 20 independent superconducting secondary coils. By reducing leakage fields around the windings, the interleaving reduces the… CONTINUE READING
