    Abstract: An electrical device includes a winding, a primary cooling system, a secondary cooling system, and an actuator. The winding includes an interior portion and an exterior surface. The primary cooling system cools the exterior surface of the winding. The secondary cooling system cools the interior portion of the winding. The actuator is configured to actuate the secondary cooling system in response to a sensed condition of the electrical device or a predicted condition of the electrical device.

    Abstract: A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.
