Patent number: 11641101Abstract: A method includes detecting an initial fault in a system and opening a contactor to isolate a load bus from the system for a window of time. During the window of time, the method includes detecting whether current flows from a generator of the system. If current flows from the generator of the system during the window of time, the method includes isolating the load bus from the generator. If current does not flow from the generator to the system during the window of time, the method includes isolating the load bus from all sources including the generator.Type: GrantFiled: April 2, 2021Date of Patent: May 2, 2023Assignee: Hamilton Sundstrand CorporationInventors: Joshua Berg, Jef William Good, John F. Defenbaugh

Patent number: 11300600Abstract: In accordance with one or more embodiments, a system is provided. The system includes feeders, sensors, and a controller. The feeders connect a panel to a generator and a load. The sensors are on the feeders. The controller receives sensor signals from the sensors. The controller evaluates the sensor signals to determine a fault location.Type: GrantFiled: March 18, 2020Date of Patent: April 12, 2022Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: John F. Defenbaugh, Jef William Good, Joshua Berg

Patent number: 9948110Abstract: An example power distribution system includes a relay moveable to a position that holds at least one contactor closed. The relay is moved to the position in response to an alternate source powering a power distribution system rather than a main source powering the power distribution system.Type: GrantFiled: May 21, 2012Date of Patent: April 17, 2018Assignee: Hamilton Sundstrand CorporationInventors: Robert L. Seagren, Joshua Berg, Dennis Strong, Jomar Avancini Rocha

Patent number: 9789973Abstract: A controller is employed in conjunction with an electrical power distribution system (EPDS). The controller includes at least a first input for receiving DC power from a DC power bus and a power supply circuit connected to the first input to provide operational power to the controller. The controller further includes a power interrupt bridge circuit that monitors the voltage provided of the first input. In response to the monitored voltage being less than a threshold value, the power interrupt bridge circuit supplies power to the power supply circuit from a DC emergency source for a defined time period.Type: GrantFiled: April 5, 2012Date of Patent: October 17, 2017Assignee: Hamilton Sundstrand CorporationInventors: Paul Swearingen, Robert L. Seagren, Joshua Berg

Patent number: 9018799Abstract: An electrical system architecture has at least two sources of electrical power, each delivering power to an individual AC bus. The individual AC buses are connected by a tie bus. A first source of electric power delivers power into a first AC bus, and the first AC bus delivers power to a first set of users. A supply current sensor is between the first source of power and the first AC bus. A tie bus output sensor senses output power from the AC bus being delivered onto the tie bus. A plurality of user output current sensors sense current passing to each of the plurality of users. A control is operable to compare a sensed current in the supply current sensor, and sum the current in the tie bus output sensor, and the plurality of user output sensors. If the sum of the output sensors differs by more than a predetermined amount from the current sensed by the supply sensor, the control identifies a fault. The first AC bus is then disconnected from the tie bus.Type: GrantFiled: May 24, 2012Date of Patent: April 28, 2015Assignee: Hamilton Sundstrand CorporationInventors: Jef William Good, Robert L. Seagren, Joshua Berg

Publication number: 20140309818Abstract: A ram air turbine deployment module includes a normal power module that determines if normal power from an aircraft is available, an air-ground module that determines if the aircraft is off the ground, a ground-maintenance module that determines if the aircraft is presently having maintenance preformed, and decision logic that provides an output to a ram air turbine that deploys the ram air turbine if normal power from the aircraft is not available, the aircraft is off the ground, and the aircraft is not presently having maintenance performed.Type: ApplicationFiled: April 15, 2013Publication date: October 16, 2014Applicant: Hamilton Sundstrand CorporationInventors: Robert L.
