Abstract The normal zone propagation velocity (NZPV) of three families REBCO tape architectures designed for superconducting fault current limiters and to be used in high voltage direct transmission systems has been measured experimentally liquid nitrogen at atmospheric pressure. NZPVs span more than orders magnitude depending on the architectures. Numerical simulations based finite elements al...

The growing rate of energy consumption is a reason for establishment of new power plants which leads to increment in fault current level. One of the solutions to overcome this problem is utilization of fault current limiters (FCLs). Another concerning issue in energy generation is the satisfactory voltage quality in grid and to deal with it, a power electronic based device, known as dynamics vo...

The algorithms of the present generation practical differential relays are based on two methods. first method is ratio harmonic content current, and second one length time interval between zero-crossing points called gap-detection method. However, these methods suffer from installation fault current limiters (FCLs) in power system transformer (CT) saturation phenomenon. This paper deals with a ...

BACKGROUND The quench process in high-temperature superconducting (HTS) wires plays an important role in superconducting power devices, such as fault current limiters, magnets, cables, etc. The superconducting device should survive after the overheating due to quench. METHODS We studied the evolution of the resistance of the YBCO tape wire during the quench process with 1 ms time resolution f...
