Power distribution systems and method of the operation of a power distribution system forms, including arcing detection

摘要

Described is a arcing relay system (136) for use in a power distribution system, comprising a arc rollover sensor (138), a first circuit protective device (104, 106) and a second circuit protective device (102, 142). To the arcing relay system (136) includes a first input, which is adapted to a detection signal from the arc rollover sensor (138), a second input, which is adapted to a blocking signal from the first circuit protective device (104, 106); and a control device. The control device is configured for this purpose, at least partially on the basis of the detection signal to determine whether a transfer has occurred. The control system activates the second circuit protective device (102, 142) in response to the determination that a transfer has occurred if the control device receives the blocking signal is not delayed, and an activation of the second circuit protective device (102, 142) in response to the determination that a transfer has occurred if the control device receives the blocking signal.
