Over 92.8% of the insulator of insulator on the existing circuit in operation is able to meet security demand that the circuit operates now.

现有的正在运行的线路上的绝缘子超过92.8%的绝缘子是能够满足现在线路运行的安全要求的。

As the power systems expand, the fault currents would be increase to exceed the instantaneous capacity and the interrupting capabilities of the existing circuit breakers.

电力系统的容量和短路电流越来越大，相应的对系统的稳定性和断路器的开断能力等提出了更高的要求。

In this case the short circuit level is way above the existing interruptive capacity.

在这种情况下，短路水平大大高于现有的中断能力。
