Strict theoretical deduction shows that adaptive current fast - tripping protection can be used not only on single - circuitline, but also on double - circuit line.
It is very complicated to design large capacity of power distribution project through making singleline drawing, calculating short circuit current and selecting products.
在大容量配电设计中，绘制单线图、计算短路电流和产品选型是很复杂的。
