Abstract

A superconducting winding includes a pair of superconducting winding sections electrically connected at a node and bypass circuitry connected between the node and electrical ground and configured to allow current to flow to electrical ground when a voltage across the superconducting winding exceeds a predetermined threshold voltage. In certain embodiments, the bypass circuitry includes a switching device (e.g., zener diode) having an open position and a closed position, the switch in the closed position to allow current flow when the voltage across the superconducting winding exceeds the predetermined threshold voltage.
