Company Plans Power ‘Valve’ Employing Superconductors
August 18, 2003 | Source: New Scientist
To suppress surges, Intermagnetics General plans to use superconductors as valves on the electric-utility power grid, letting their temperature rise to choke off the flow of power. The device would also generate a magnetic field, which further lowers superconductor conductivity.
The idea is to reduce the surge to a level that conventional circuit breakers can handle.
