The decision circuit of the chip is applied with a DFF using SCFL structure and its tuned phase shifter with differential current amplifiers according to the principle of vector addition.
该芯片的判决电路采用SCFL(源级耦合晶体管逻辑)的D触发器结构，根据矢量叠加原理设计，采用差动电流放大器构成可调移相器。
It also can improve the bandwidth of transmission widely when using E1 rate to transmit current differential information. This can be used by the protection to enhance its performance.
同时，使用E1速率来传输电流差动信息后，也使得保护信息传输带宽大大加宽，有利于保护功能的增强与完善。
The transformation ratio of the original current transformer (CT) on the transformer HV side was so large that a parameter for the differential protection software exceeded its settable scope.
因变压器高压侧的电流互感器选择变比过大，以致超出差动保护软件的参数设置的范围。
