Abstract: A solid-state circuit breaker (SSCB) comprises a breaker housing, line-in and line-out terminals and one or more solid state switching components. The SSCB further comprises an air gap disposed between the line-in and line-out terminals and coupled in series with the solid-state switching components to complete a current conducting path when closed. The air gap includes an air gap driving mechanism. The solid-state circuit breaker further comprises an air gap actuator to interact with the air gap driving mechanism. The SSCB further comprises a controller that controls the air gap actuator and is configured to: (a). send a tripping signal to the air gap actuator and the one or more solid state switching components at substantially the same time or (b). send a tripping signal to the air gap actuator a short amount of time earlier than sending the tripping signal to the one or more solid state switching components.

Abstract: A method of overpower protection in a power supply system for driving a light source includes determining a voltage drop across a voltage-controlled resistor (VCR) coupled in series with the light source, calculating a power dissipation of the VCR based on the voltage drop and an output current of the power supply system, determining whether the power dissipation is greater than a power threshold, and in response to determining that the power dissipation is less than or equal to the power threshold, determining that an accumulated energy of the VCR is greater than zero, and decrementing the accumulated energy based on the power threshold and the power dissipation of the VCR.

Abstract: Described herein are improvements for a power system by operating the power system using updated performance characteristics for a protection device. In one example, a method includes operating the power system based on a first operational curve for a first protection device of the one or more protection devices. The first operational curve indicates conditions upon which the first protection device will trip. The method also provides obtaining trip information describing conditions that cause the first protection device to trip at each of one or more trip occurrences during operation of the power system. The method further provides adjusting the first operational curve to generate an adjusted first operational curve that reflects the trip information and operating the power system based on the adjusted first operational curve.

Abstract: In a method for monitoring a high-voltage DC transmission the following are predefined: an amperage threshold value for an amperage of the high-voltage DC transmission, at least one interval length for time intervals and, for each predefined interval length, a change threshold value for a change in the amperage averaged over time intervals of the interval length. The amperage for each terminal of the high-voltage DC transmission is determined, and a change in the amperage averaged over time intervals of the interval length is determined for each predefined interval length. A DC error is determined if the magnitude of the amperage of at least one terminal is greater than the amperage threshold value or if, for an interval length, the magnitude of the averaged change in the amperage of at least one terminal is greater than the change threshold value predefined for the interval length.

Abstract: Methods and systems for detecting a falling power line in a power transmission or distribution system are described. Electrical measurements at various points in the power distribution system are used to detect changes in a power line indicating that the conductor has broken or become disconnected. Upon detection, control mechanisms are used to deenergize the conductor while the conductor is falling and/or before it contacts the ground.
