A dynamic mathematical model-Johns arc model which could be used to simulate the dynamic secondary arc in the process of single-phase auto-reclosure after transient single-phase faults is presented and actualized in PSCAD/EMTDC. This model is used in the digital faults simulations of the first ultra high voltage (UHV) transmission line of 1000 KV class in China-the Jindongnan-Jingmen UHV single circuit...
