摘要: A method and apparatus are provided for detecting an arcing fault on a power line carrying load current. Parameters indicative of flow possible events the line, such as voltage current, monitored analyzed arc burst pattern exhibited by faults in system. These detected identifying bursts each half-cycle fundamental Bursts occurring at or near peak indicate that phase. Once faulted phase is identified, comparison current reveals whether located downstream direction toward customers, upstream generation station. If downstream, de-energized, if upstream, may remain energized to prevent unnecessary outages.
