A NEW APPROACH TO THE ARCING FAULTS DETECTION FOR FAST AUTORECLOSURE IN TRANSMISSION-SYSTEMS

To avoid automatic reclosing on permanent faults, a new numerical algo rithm for arcing faults detection has been developed. Some important f eatures of a long are in air are investigated and used as a base in th e algorithm design. The fact that the nonlinear are behavior influence s other voltages and currents distorting them, offered an opportunity to detect the are by measuring and processing the line terminal voltag e and current. A series of simulation studies have shown that the algo rithm can be used as an effective tool for arcing faults detection.
