阻抗分量

It simulates the circuit breaker with a zero impedance branch, and adopts the linear network characteristic and theory, variable structure and variable parameter analyses to transfer the short-circuit current flow in the bus-bar equality into each side of circuit breaker, and deduces the sequence component model and algorithm for calculating the short-circuit current of circuit breaker when the short-circuit fault occu...

该方法将断路器作为一条阻抗为零的支路来模拟，运用线性网络特性、定理及变结构与变参数的分析方法，将母线上短路时的短路电流等值转移到断路器两侧，导出了相当于在断路器两侧分别发生短路故障时，流过断路器的短路电流的序分量模型和算法。

Because the magnetoelectricity characteristic of TA is not linear, huge short-circuit current or large nonperiodic current may make the TA enter the saturated state, which cause the exportation current of the TA very small, making the busbar differential current very large.

母线区外故障时，由于带铁心TA 激磁电感的非线性特性，强大的短路电流及较大的非周期分量都可能使TA 进入深度饱和状态，此时TA 的励磁阻抗将变得很小，一次电流大部分流入励磁支路，导致TA 输出电流很小，使得母线保护差动电流很大，如果不采取一定的措施，极易发生误动。

Each signal component will see a different impedance for each signal line to its return path and each signal component may also travel at a different velocity.

正确的翻译应该是：每个信号分量将在每个信号线与它的返回路径间看到不同的阻抗，同时也以不同速度传播。
