In order to improve the measurement accuracy of luminometer and ensure linear relationship of the photoelectric, operational amplifiers is designed as current-voltage converter form, on the one hand, it is available to zero-load effect; on the other hand, short-circuit current can be transformed into a voltage volume through the feedback resistor, it is equivalent to voltage drop flowed through a load resistor on the actual effect.

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。

This reduces the impact of a short circuit and assures that the bus does not conduct current through the aircraft. A Manchester code is used to present both clock and data on the same wire pair and to eliminate any DC component in the signal (which cannot pass the transformers). The bit rate is 1.0 megabit per second (1 bit = 1 μs).
