System And Method For Quench Protection Of A Superconductor

Abstract: A system and method for protecting a superconductor (12) from a quench conditoin. A quench protection system (18) is provided to protect the superconductor (12) from damage due to a quench condition. The quench protection system (18) comprises a voltage detector (20) operable to detect voltage across the superconductor (12). The system (18) also comprises a frequency filter (22) is operable to couple voltage signals to a control circuit (26) that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system (18) is operable to detect whether a quench condition exists in the superconductor (12) based on the voltage signal received via the frequency filter (22) and to initiate a protective action in response.
