输电线路在运行过程中承受工作电压、操作过电压或大气过电压时，都可能会发生绝缘闪络事故。

When bearing operating voltage, switching overvoltage or atmospheric over-voltage in the process of operating, the transmission line are likely to occur insulation flashover accident.

目前随着更高工作电压的使用，由于断路器分闸、合闸操作所引起的电压暂态过程或过电压．已成为主要考虑的方面。

With the much higher operating voltages now in use the projected voltage transients or surges due to switching i. e. the opening and closing of circuit breakers, have become the major consideration.
