1·Application of unconventional mutual inductor in the digital substation is widen increasingly.
非常规互感器在数字化变电站中的应用日益广泛。
2·The short circuit current calculation shows the rated thermal stability current of former current mutual inductor is too small.
通过计算短路点的短路电流，说明原电流互感器额定热稳定电流太小。
3·Discussing the principle and technical design of special-purpose loading box for small current mutual inductor.
论述了小电流互感器专用负载箱的原理及技术设计。
