The control system had the self-diagnosis function and preparation of the signal output and input terminals. 控制系统有故障自我诊断功能,并预留讯号输出与输入端子。
According to the direct current component of the generalized instantaneous power flowing into the two-terminal network, magnetizing inrush and internal fault can be distinguished. 根据输入端口的广义瞬时功率直流分量的大小,来区分励磁涌流和内部故障电流。
