Copyright policy )Short-Circuit Tests and Simulations with a SCFCL Modular Assembly
AbstractShort-circuit tests and simulations carried out with a resistive SCFCL modular assembly are presented. Each SCFCL moduleconsistsofaBSCCO2212bulkcoilwithacritical currentofabout520Aat77K.Seriesandparallel connection were tested. In series connection, prospectivecurrent as high as 67 kArms was limited to about 11 kApeak in the first peak. In parallel connection, prospective current as high as 65 kArms was limited to about 20 kApeak in the first peak. Low fault current tests were also carried out (current peaksof about3Ic)and in this case the SCFCL module takes more time to actuate, being considered satisfactory for “inrush” currents. Computational simulations were done considering the bulk coil E-J curve and heat transfers between SCFCL components and the LN2 bath. The simulations can reasonably predict the performance of the SCFCL assembly and provide additional information such as the temperature rise of superconductor and shunt.
