Patent number: 10680434Abstract: A fault current limiter (FCL) includes at least one magnetisable core member and at least one AC magnetomotive force source configured to generate a varying magnetic flux in at least a portion of the at least one magnetisable core member. At least one static magnetomotive force source is positioned to provide a magnetic circuit within at least part of the at least one magnetisable core member and the AC magnetomotive force source and the static magnetomotive force source are relatively positioned to be orthogonal to each other. Typically the static magnetomotive force source may be a permanent magnet and the AC magnetomotive force source configured to generate a varying magnetic flux in both of first and second spaced core members.Type: GrantFiled: April 24, 2017Date of Patent: June 9, 2020Assignee: Faultcurrent LimitedInventor: Jeremy Peter Hall

Publication number: 20180175614Abstract: A fault current limiter (FCL) has a core structure with a first and second magnetisable core members and an AC magnetomotive force source configured to generate a varying magnetic flux in at least a portion of the first and second magnetisable core members. Static magnetomotive force sources being positioned to provide a magnetic circuit within at least part of the magnetisable core members. The FCL may have a ring core structure and the static magnetomotive force sources may include a mitred or tapered joint interface with the core member.Type: ApplicationFiled: February 27, 2014Publication date: June 21, 2018Applicant: Faultcurrent LimitedInventor: Jeremy Peter Hall
