Abstract

See full text

The fault current limiter in a cryogenic liquid heat transfer medium, employs a high temperature superconductor (HTS) element which has a high thermal resistance coating material encapsulating the high temperature superconductor to form an intermediate boundary layer between the HTS element and the heat transfer medium. The coating material has a thickness which enables it to minimize the retained heat in the HTS element during recovery from a fault condition, wherein substantially all heat transfer from the encapsulated high temperature superconductor element to the liquid cryogen heat transfer medium occurs at the nucleate boiling heat transfer rate.
