The operation characteristics of fast trippingcurrent protection, adaptive current protection and distance protection are compared.
比较了电流速断、自适应电流速断及距离保护的动作特性。
2
When regulating current, the instantaneous trippingcurrent must larger than the short time delay current must larger than the long time delay trippingcurrent.
调节整定电流时，瞬时脱扣电流应大于短延时脱扣电流，短延时脱扣电流应大于长延时脱扣电流。
3
The protection range of traditional fast trippingcurrent in different connection modes can be decided according to the fast trippingcurrent protection theory.
