Superconducting fault current limiters — UK network trials live and limiting

A consortium comprising three UK Distribution Network Operators (DNOs) has deployed three superconducting fault current limiters (SFCLs) in the UK distribution system. Funding through the UK energy regulator's Innovation Funding Incentive (IFI) scheme is contributing to the DNOs' financial commitment to this project. The limiters have been supplied by Applied Superconductor Limited (ASL) which is now engaged in several additional projects including a 33kV pre-saturated core project for Northern Powergrid and a magnesium diboride based resistive limiter for Western Power Distribution.
