| Resumo | |
Most of transmission line faults are line to ground and most of them are transitory in nature. In this sense, high speed auto reclosing improves the system stability, but there must be certainty that the arc has been extinguished. For shunt compensated transmission lines, frequently, an additional single-phase reactor is connected between neutral and ground. This reactor contributes to coupling reduction and is important to reduce secondary arc current amplitude, which in turn will decrease the secondary arc extinction time during single pole reclosing This paper examines different aspects related to the neutral reactor optimization and its effects for arc extinction time reduction during three-phase reclosing. Additionally, the result of applying a switching method to reduce overvoltages during three-phase reclosing is presented. (AU) | |
