摘要： A direct current (DC) overvoltage monitoring and protection device includes an overvoltage sensor operably connected to an electrical power input line. The overvoltage sensor is configured to change state upon detection of a voltage over a preselected threshold. An overvoltage relay is operably connected to the overvoltage sensor. The overvoltage relay includes one or more relay switches configured to move between a first position and a second position when the voltage over the preselected threshold is detected. An independent relay power source is operably connected to the overvoltage relay to provide electrical power to the overvoltage relay, separate from the electrical power being monitored via the electrical power input line.

摘要： An example method for residual overcurrent protection includes determining an increment amount for residual overcurrent protection. The method further includes determining a decrement amount for residual overcurrent protection. The method further includes determining a count value based at least in part on the increment amount, the decrement amount, and a previous count value. The method further includes detecting an overcurrent condition based at least in part on the count value and a residual overcurrent limit. The method further includes controlling a generator to correct the overcurrent condition responsive to detecting the overcurrent condition.

摘要： A closing mechanism controller includes contactor operating logic that generates a software or firmware based closing mechanism command signal. The controller also includes hardware interlock circuitry that generates an interlock signal, the hardware interlock circuity being configured to compare an interlock signal to the software based closing mechanism command signal and to provide an enable signal to the closing mechanism when the interlock signal matches the closing mechanism command signal.

摘要： A system includes a first AC bus configured to supply power from a first generator. A first generator line contactor (GLC) selectively connects the first AC bus to the first generator. A second AC bus is configured to supply power from a second generator. A second GLC selectively connecting the second AC bus to the second generator. An auxiliary generator line contactor (ALC) is connected to selectively supply power to the first and second AC buses from an auxiliary generator. A first bus tie contactor (BTC) electrically connects between the first GLC and the ALC. A second BTC electrically connects between the ALC and the second GLC. A ram air turbine (RAT) automatic deployment controller is operatively connected to automatically deploy a RAT based on the combined status of the first GLC, the second GLC, the ALC, the first BTC, and the second BTC.

摘要： A power quality control circuit is connected to monitor an AC input power and selectively connect the AC input power through a contactor. The power quality control circuit includes power quality monitor circuitry that determines whether the AC input power has an overfrequency condition, an underfrequency condition, an overvoltage condition or an undervoltage condition, and prevents closing of the contactor in response to a determination of any of those conditions.

摘要： A system includes a first AC bus configured to supply power from a first AC power source. A second AC bus is configured to supply power from a second AC power source. A first transformer rectifier unit (TRU) connects a first DC bus to the first AC bus through a first TRU contactor (TRUC). A second TRU connects a second DC bus to the second AC bus through a second TRUC. A ram air turbine (RAT) automatic deployment controller is operatively connected to the first TRUC and to the second TRUC to automatically deploy a RAT based on the combined status of the first TRUC and the second TRUC.

摘要： A dual feeder circuit system for supplying electrical power can include one or more feeder groups, each feeder having a first wire and a second wire connected between a source terminal and a load terminal to carry the same electrical signal on both wires. The system can include one or more current transformers disposed on one or more of the feeders groups such that the current transformer is disposed around both the first wire and the second wire. The first wire can be passed directly through a first side of the current transformer to allow current to travel through the current transformer in a first direction, and the second wire can include a loop and be passed through a second side of the current transformer to allow current to travel through the current transformer in an second direction opposite the first direction.

摘要： 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.
