A method for blocking and detecting low impedance arc discharge of a circuit breaker for a low voltage is provided to rapidly block a circuit breaker by detecting permanent or temporary short circuit in a voltage distribution system on a real time. An arc current detecting part(110) detects an...
where the number of OCRs form j = 1 to n, tj,ktj,k is the tripping time of relay j at short-circuit current location k. The weight that defines the chance of event of a fault on a selected line is presented by W. Here, the weight value is assumed to be one [19,41], and ...
