| 20100201338 | HYBRID DISTRIBUTION TRANSFORMER WITH AC & DC POWER CAPABILITIES - A hybrid transformer is provided that includes an electromagnetic transformer and an AC-AC converter with a DC bridge. The AC-AC converter is operable to keep the input voltage and current of the hybrid transformer substantially in phase and to reduce fluctuation in the output voltage of the hybrid transformer in the event of an increase or decrease in the input voltage. | 08-12-2010 |
| 20100220499 | HYBRID DISTRIBUTION TRANSFORMER WITH AN INTEGRATED VOLTAGE SOURCE CONVERTER - A hybrid distribution transformer is provided that includes an electromagnetic transformer and a voltage source converter that is operable to reduce fluctuation in the output voltage of the hybrid distribution transformer in the event of an increase or decrease in the input voltage. | 09-02-2010 |
| 20100315190 | VERSATILE DISTRIBUTION TRANSFORMER - A versatile distribution transformer having an electromagnetic transformer and a power electronic module is provided. A pocket having connectors electrically connected to at least one winding structure of the electromagnetic transformer is mounted above the electromagnetic transformer. The power electronic module is removably mounted in a cavity of the pocket. The power electronic module includes a plurality of semiconductor switching devices and a plurality of connectors adapted to slidably engage the connectors of the pocket. The power electronic module is movable between a removed position, wherein the power electronic module is located outside the pocket, and an installed position, wherein the power electronic module is disposed in the cavity of the pocket and the connectors of the power electronic module engage the connectors of the pocket so as to electrically connect the power electronic module to the at least one winding structure. | 12-16-2010 |

| 20080201020 | ADAPTIVE PROVISION OF PROTECTION FUNCTION SETTINGS OF ELECTRICAL MACHINES - A protection setting determiner ( | 08-21-2008 |
| 20090091416 | Wirelessly Powered Secondary Electrical Distribution Equipment - A wireless secondary assembly is disclosed for use in an electrical distribution network. The secondary assembly may include a wireless source electrically connected to a first electric cable and adapted to emit an electromagnetic power signal. A wireless receiver is electrically connected to a secondary device and adapted to receive the electromagnetic power signal and convert the electromagnetic power signal to electricity to power to secondary device. | 04-09-2009 |
| 20100082844 | FIELD DEVICE CONTROLLER ADAPTER - A controller adapter including a controller interface configured to interface with a controller for a legacy field device of an electrical power distribution system, wherein the controller communicates based on a first protocol, a network interface configured to interface with a network common to a plurality of assets of the electrical power distribution system, wherein the network interface communicates based on a second protocol, a mapper that maps information received from the legacy field device controller about the legacy device that to the second protocol, and storage that stores at least one logic function, wherein at least one input and/or output of the logic function is connected to the mapped information. | 04-01-2010 |
| 20100230263 | CUTOUTS WITH AUTOMATIC RECLOSING - A cutout is used in an electrical distribution network to electrically connect a first electric cable with a second electrical cable, The cutout includes an electrically non-conductive insulator having first and second end. A first terminal assembly is secured to the first insulator end. A second terminal assembly is secured to the second insulator end. A failsafe fuse assembly is pivotally secured to the second terminal and is movable between an engaged position and a lockout position. A reclosing mechanism is secured to the first terminal and monitors electrical current through the fuse assembly. If a fault condition exists, the reclosing mechanism opens and then closes the electrical link between the first and second electrical cable. If, after a predetermined number of closes, the fault condition still exists, the reclosing mechanism disconnects from the fuse assembly, allowing the fuse assembly to fall to the lockout position. | 09-16-2010 |
