ARCING FAULTS DETECTION ON POWER-LINES FROM THE VOLTAGE AND CURRENT SIGNALS

To avoid automatic reclosing on permanent faults, a new digital algori thm for arcing faults detection has been developed. Some important fea tures of a long are in the air are investigated and used as a base in the algorithm design. The fact that the nonlinear are behavior influen ces other voltages and currents distorting them, offered an opportunit y to detect the are by measuring and processing the line terminal volt age and current. A series of simulation studies have shown that the al gorithm can be used as an effective tool for arcing faults detection.
