Abstract
One embodiment of the invention provides a method, system, and device for the auto-reclosing a faulted power transmission line by measuring the characteristics of voltage on a faulted line to determine, in real-time, the moment that the secondary arc is extinguished. A device automatically selects between a plurality of arc extinguishing algorithms based on the compensation level of the transmission line. As a result, reclosing an on-going or existing fault is avoided, while restoration of normal power supply is performed with the minimal possible time interval.
