BUFFER FOR DECISION MAKING ON DISCONNECTION IN ADAPTIVE DETECTION OF SHORT CIRCUIT THROUGH ARC Russian patent published in 2018 - IPC H02H3/00 

FIELD: electricity.

SUBSTANCE: device for detection and filtration of undesired events of disconnection of short circuit through an arc contains: a storage to store data of one or more types of events of disconnection of short circuit through an arc, previously detected in a circuit within a certain period of time, with each previously detected type of event of disconnection of short circuit through an arc leading to the interruption of the circuit at least once, if detected; and a processor, which communicates with the storage, while the processor is adapted to determine whether the newly detected event of disconnection of short circuit through an arc is an undesired event of disconnection, based on the number of times of one and the same type of the event of disconnection of short circuit through an arc, which occurred earlier, as a newly detected event of disconnection of short circuit through an arc, and to forbid the interruption of the circuit if the newly detected event of disconnection of short circuit through an arc is determined as an undesired event of disconnection.

EFFECT: providing filtration of undesired events of disconnection of short circuit through an arc.
