Transient magnetic simulation of the fault current limiter with QuickField. Webinar fragment.

QuickField simulation example prepared by Professor James R. Claycomb as a part of the webinar Fault Current Limiter Simulations using QuickField. Model files and more details are at https://quickfield.com/advanced/fault... An inductive superconducting current limiter protects the primary circuit. When the high voltage surge arrives, the current should be limited. The superconductor effectively screens the secondary winding. When the fault occurs, the current increases many times, and its magnetic field causes the superconductor to come to a normal state. The secondary winding is no more screened and effectively increases the impedance of the circuit, thus limiting the fault current.
