HTS Components for High Voltage Resistive Current Limiters Based on a Magnetic Field Triggered Concept

On the basis of the successful field test of the current limiter CURL 10 a superconducting resistive current limiter for the transmission level is projected (CULT 110). It is also based on melt cast processed BSCCO 2212 but uses a novel protection concept via magnetic field triggering, which reduces the needed superconducting length by nearly one order of magnitude. The present state of development of the superconducting components including the optimization of the magnetic trigger coils is reported. Numerical simulations confirm the reliability of the protection mechanism. First successful short circuit experiments with full-scale components are presented.
