| 20100188786 | Fault Current Limiter - A method is for suppressing induced steady state and transient currents and voltages in the DC circuit and coil of a magnetically saturated core fault current limiter. The method includes the steps of: (a) providing a first current coil connected to a DC power source surrounding the core for magnetically saturating the core; and (b) providing a second resistive current coil surrounding the core and either short circuited or interconnected to the DC power source in parallel to the first current coil and wound around the core in a forward or reverse sense to the first current coil. | 07-29-2010 |
| 20100254048 | High Voltage Fault Current Limiter Having Immersed Phase Coils - A fault current limiter including: a ferromagnetic circuit formed from a ferromagnetic material and including at least a first limb, and a second limb; a saturation mechanism surrounding a limb for magnetically saturating the ferromagnetic material; a phase coil wound around a second limb; a dielectric fluid surrounding the phase coil; a gaseous atmosphere surrounding the saturation mechanism. | 10-07-2010 |
| 20100296217 | Fault Current Limiter - A fault current limiter (FCL) includes a series of high permeability posts ( | 11-25-2010 |
| 20100309590 | High Voltage Saturated Core Fault Current Limiter - A fault current limiter designed for connection into a medium voltage, high voltage, or extra-high voltage substation or other high voltage source such as a generator station, the limiter including: a ferromagnetic circuit formed from a ferromagnetic material and including at least a first limb, a second limb and a third limb; a first input phase coil wound around the first limb, a second output phase coil wound around the third limb; a saturation mechanism surrounding a limb for magnetically saturating the ferromagnetic material; a containment vessel providing a substantially uniform, low electrical conductivity medium surrounding the ferromagnetic circuit, the phase coils and the saturation mechanism. | 12-09-2010 |
| 20110116199 | Power Dampener for a Fault Current Limiter - A method of dampening a transient in a DC biasing coil in a fault current limiter, the method including the step of: interconnecting a transient suppression circuit across the DC biasing coil, the transient suppression circuit being operative when the transient voltage across the DC biasing coil exceeds a predetermined maximum. | 05-19-2011 |
