Systems, methods, and apparatus for indicating faults within a power circuit utilizing dynamically modified inrush restraint |
摘要 |
A faulted circuit indicator comprises a processor, which dynamically determines a conductor de-energization level based on a monitored average current. This dynamically-determined de-energization level and/or monitored average current may be used to provide dynamic inrush restraint and/or dynamic backfeed restraint (reset restraint). If current within a power conductor falls below the determined de-energization level, the processor determines that the conductor has de-energized, and accordingly ignores high current spikes less than a predetermined duration that occur during re-energization.
