Abstract
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.
Claims35
A fault current limiter (FCL) comprising:
- a core structure comprising
- i) a first magnetisable core member, and
- ii) a second magnetisable core member, spaced from the first core member;
- 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;
- and
- a plurality of static magnetomotive force sources being positioned to provide a magnetic circuit within at least part of the magnetisable core members.
