| 20100257864 | REVERSE FLOW CERAMIC MATRIX COMPOSITE COMBUSTOR - A gas turbine engine has an annular reverse-flow combustor with a combustor inner liner enclosing a combustion chamber. The inner liner having a dome portion at an upstream end of the combustor and a downstream combustor exit defined between a small exit duct portion and a large exit duct portion. At least one of the dome portion, the small exit duct portion and the large exit duct portion is made of a separately formed hemi-toroidal shell composed of a ceramic matrix composite. | 10-14-2010 |

| 20090147412 | Transformer inrush current detector - A differential protection system for power transformers using Rogowski coils as current sensors can support an inrush current detection method based on sensing lows in the derivative of the sensed current. Effective detection of power transformer inrush conditions can enable blocking of a protection relay during inrush where the differential current may exceed a differential threshold value indicative of a fault without the presence of an actual fault. The outputs of the Rogowski coils, being proportional to the first time derivative of the sensed current, may be useful in the inrush detection method. Also, with reduced saturation concerns, the Rogowski coil protection system may employ a single slope response with increased sensitivity. A discrete time sampling technique for identifying low di/dt portions within the sensed current also may be useful in detecting power transformer inrush conditions. | 06-11-2009 |
| 20090230948 | Rogowski Coil Assembly and Methods - A Rogowski coil assembly includes a first Rogowski coil that surrounds a conductor and generates a first voltage output signal. A second Rogowski coil also surrounds the conductor. The second Rogowski coil generates a second voltage output signal. A relay device communicates with the first and second Rogowski coils and processes the first and second voltage output signals. For example, the relay device can process the voltage output signals to calculate an amount of noise in the first and second output voltage signals and/or to minimize the amount of noise in the first and second output voltage signals. | 09-17-2009 |
| 20100020457 | Protective Digital Relay Device - Relay devices, systems and methods for obtaining an accurate representation of a current monitored with a Rogowski coil, without integration of the Rogowski coil output voltage signal in the time domain. | 01-28-2010 |
