摘要： In a power protection and distribution assembly a trip system monitors electrical current and sends a current status signal to an arc flash protection system indicating whether current characteristic of an arc event is detected. The arc flash protection system evaluates this current status signal along with a light status signal indicating whether light characteristic of an arc event has been detected. Based on this evaluation, the arc flash protection system sends a control signal to the trip system for controlling the trip system to trip a breaker. The systems each include a full-duplex signaling module for sending the signals between the systems over a pair of conductors. Each signaling module sends one of the signals by modulating the magnitude of a current through or a voltage across the conductors, and receives the other signal by demodulating the magnitude of the current through or the voltage across the conductors, as distinctively modulated by the other signaling module.

摘要： Received power line trip signals are delayed in their tripping function by a circuit which causes introduction of the delay in response to a wideband received signal rising rapidly above a dynamic amplitude level, or in response to a narrowband received signal going outside upper and lower amplitude limits. Either condition could indicate a false trip signal, so that a delay before actual tripping is desirable.

摘要： The present disclosure pertains to systems and methods for supervising protective elements in electric power systems. In one embodiment, a system may be configured to selectively enable a protective action an electric power system. The system may include a data acquisition subsystem receive a plurality of representations of electrical conditions associated with at least a portion of the electric power delivery system. An incremental quantities module may calculate incremental quantities from the plurality of representations. A protective module may be configured to detect an event, to determine an incremental quantities value during the event, and to determine a time-varying threshold. The incremental quantities value during the event may be compared with the time-varying threshold, and a protective action module may be enabled to implement a protective action when the value of the incremental quantities value during the event exceeds the time-varying threshold.
