文摘
- •
Optimal instant for simultaneous closing strategy to reduce transformer inrush current is proposed.
- •
Independent-pole-operated circuit breaker is not required.
- •
Optimal switching instant is analytically obtained.
- •
The method has been tested in ATP/EMTP simulations and the expected results have been obtained.
- •
Simulations considering the effect of circuit breaker pre-arcing have shown a higher reduction of the inrush current.
