This paper describes in detail techniques that have been developed to model arcing faults. These techniques are used to simulate arcing faults of six phase transmission lines. The primary arc is modeled using a time dependent dynamic resistance. The secondary arc is modeled using a controlled switch and a time dependent dynamic resistance. The switch is used to simulate the reignition and extinction voltage characteristic of the secondary arc. The arc model is then employed for the simulation of fault transients of short-distance uncompensated line and a long-distance compensated line. The compensation schemes are necessary for reducing the secondary arc current and recovery voltage to levels commensurate with rapid extinction in long-distance lines. This study is needed to design single phase adaptive autoreclosure schemes and new protection techniques.
