The commercial applications of Superconducting Fault Current Limiters (SFCL) in electrical power systems are enormously increasing due to the production of long length high temperature superconducting (HTS) tapes. SFCL are preferred in electrical utility networks due to their better technical performance during faults when compared with the conventional Circuit Breakers. The self triggering...
Explored in the framework of the Research Training Group “Lorentz Force Velocimetry (LFV) and Lorentz Force Eddy Current Testing”, the target of this work is to develop the Lorentz Force Flow-meter (LFF) – a contactless technique for flow rate measurement of conducting liquid. By measuring the reaction force of magnetic source, induced by eddy currents, the flow rate of fluid with known...
This work describes electromagnetic, mechanical and thermal modeling studies of conduction cooled MRI magnets wound using MgB2 and Nb3Sn superconducting strands. The goal is to substantially decrease the whole system cost and sitting cost by reducing the conductor needed, as well as the system footprint and sitting requirements. In this work we present magnet designs optimized for the...
A pulsed, modular HTS electromagnet for energy storage applications was constructed and tested. Charge and discharge pulses are accomplished in about one second. A recuperative cryogenic cooling system supplies 42 to 80 Kelvin helium gas to the electromagnet. A practical solution to overvoltage and overcurrent protection has been implemented digitally using LabVIEW. Voltages as little as 46...
