文摘
- •
Transients caused by switching of three-phase 420 kV variable shunt reactor (VSR).
- •
Model in EMTP-RV software with dynamic electric arc in SF6 circuit breaker.
- •
Inrush currents due to VSR energization and overvoltages due to de-energization.
- •
Overvoltages due to electric arc reignition.
- •
Mitigation measures and operating switching strategy of VSR were proposed.
