US 10,784,673 B2 · Current protection device with mutual reactor

Abstract

Embodiments of the disclosure provide a current protection device with a mutual reactor including a first winding and a second winding. The current protection device is a subcomponent of a previously developed fault current limiter. The current protection device protects the superconductor from potential damage. The current protection device may include a coil electrically connected in series with the first winding or the second winding, an actuator mechanically coupled at an output of the coil, and an electrical interrupter electrically connected to the first and second windings, wherein the actuator is communicatively coupled with the electrical interrupter to actuate a moveable contact of a set of breaker contacts of the electrical interrupter. In some embodiments, the first and second windings are arranged in parallel to one another. In some embodiments, the coil is electrically coupled to an output of the first winding or the second winding.
