由于我们目前的箱子也可能产生其他小故障电流，我们需要此信息，以便关闭断路器（RCD）没有任何流动的小变化。
Since our current boxes could also produce other small fault currents, we need this information so turn off the circuit breaker (RCD) not for any small variation of the flow.
KA5为跳闸报警继电器。当设备产生偏励磁、可控硅故障、过电流等故障时，KA5吸合，断路器分励线圈得电跳闸，切断主电源。
When there are bias excitation, controllable silicon failure, over current and other failures, KA5 gets absorbed and breaker loop trips by powered on so as for switching off main power supply.
如有故障发生，熔断器会断开，使所有故障电流流经跳闸线圈，将断路器断开。
If a fault occurs, the fuse ruptures diverting all the fault current through the trip coil, tripping the breaker.
该文指出整流式故障电流限制器在限流过程中降低了短路电流幅值，改变了短路电流波形，明显地影响到高压断路器的关合开断能力。
The rectifier type FCL not only reduces the amplitude of short circuit currents but also changes their waveform which seriously affects the making and breaking capability of HV circuit breakers.
断路器遇故障分断后，智能控制器能显示出故障类别、故障相序及故障电流值、分断动作时间值。
Type of fault, phase sequence, value of faulty current and breaking action time will be indicated on the intelligent controller promptly if breaker turns off because of faults.
