要約(英語): The practical prediction method was studied and evaluated for transmission line voltage after circuit breaker open, where d.c. voltage remains. In case of reactor compensated lines, oscillating voltage appears with a frequency determined by line to earth capacitance and reactor at the end of line. As the line side voltage wave also includes subsidiary oscillation by phase to phase capacitance and dumps by charge leakage along supporting insulators, high-speed processor is required to predict the voltage wave by fitting or pattern recognition methods. Limited parameters such as line voltage frequency and its phase angle make very fast wave analysis feasible within 0.1 seconds using general purpose processors. Controlled reclosing of transmission line utilizing the prediction method is evaluated by numerical analysis to reduce switching overvoltage satisfactory.
