Compparison of SFCL Principles

iSFCL Characteristics

The inductive shielded superconducting fault current limiter „iSFCL“

• is based on 40 mm wide Bruker BEST 2G YBCO HTS tapewith very good performance regarding current rating and uniformity

• leading to advantageous operational properties in connection with thechosen physical FCL principle

Self activation, no external trigger circuit

Self recovery

Low operating costs

Potential to shrink size/weight considerably

Successful Milestone Oct 2009:iSFCL design passed field spec test

• Rings out of 40 mm YBCO HTS tapes with shunt system

• Limitation of 68 kA prospective current to 9 kA peak in < 5 ms

• Reaction time of ~ 0,3 ms and „self recovery“ within ~ 0,2 s

• Power rating of Modul 123 kVA

• homogeneous and simultaneous quench behaviour potential for more compact design, cost reduction

„Self-recovery“

Induktiv geschirmter supraleitender Strombegrenzer„iSFCL“

Aufbauend auf der Materialentwicklung von 40 mm breitenYBCO HTS Coated Conductors ist unser Ziel, die Vorteile dessupraleitenden Strombegrenzers an Prototypen im MS-Netzzu demonstrieren und bei Erfolg in marktgängige Produkteumzusetzen:

• Schaltverhalten- Reaktionszeit- Erholungszeit- Selbstauslösung

• Konstruktion/Investitionskosten

• Betriebskosten

• Kompaktheit !?
