Switching over-voltages in UHV systems.

Abstract: Switching overvoltages (SOV) are of concern in transmission networks operating at Ultra High Voltage (UHV) levels. This paper addresses the switching transients when a long UHV line (1200 kV) is charged. The highest switching transients occurring due to the closing/reclosing of the circuit breaker connecting the transmission line were computed using the Electromagnetic Transients...
