Abstract
A quench protection system for a superconducting machine, such as a superconducting generator having a plurality of series-arranged superconducting coils, includes at least one switch heater electrically coupled to each of the superconducting coils. A quench protection switch is provided in series with the coils, wherein each switch heater is in thermal contact with the quench protection switch. A heater network is configured in parallel with the quench protection switch and is in thermal contact with each of the coils. A quench of any one of the coils triggers a quench of the quench protection switch, wherein the heater network then triggers a quench of all of the remaining coils.
