Transient power quality issues have been becoming extrusive, such as voltage well, voltage sag and voltageinterruption, and bring customers amount of loss.
暂态电能质量问题越来越突出，如电压跌落、骤升、短时断电等现象经常发生，给用户带来了很大的损失。

Faster interruption of circuit breakers in the transmission voltage offers significant advantage to the transmission system.
断路器在输电电压下的快速开断对输电系统是明显有利的。
