这种歧视是前一种歧视的演变。设置
因此，该策略基于逐步增加当前阈值
当我们接近

比较保护装置的时间-电流跳闸曲线。
这种协调：
•易于学习和实施；
•相对便宜；
•能够实现甚至更高的歧视水平，这取决于I

the tripping curves of the protection devices. The discrimination limit is given by the minimum magnetic threshold of the circuit-breaker upstream, XT1B160 In160. Time discrimination This type of discrimination is an evolution from the previous one. The setting strategy is therefore based on progressively increasing the current thresholds and the time delays for tripping the protective devices as we come closer to the power supply source. As in the case of current discrimination, the study is based on a comparison of the time-current tripping curves of the protective devices. This type of coordination: • is easy to study and implement; • is relatively inexpensive; • enables to achieve even high discrimination levels, depending on the I cw of the upstream device; • allows a redundancy of the protective functions and can send valid information to the control system, but has the following disadvantages: • the tripping times and the energy levels that the protective devices (especially those closer to the sources) let through are high, with obvious problems concerning safety and damage to the components even in zones unaffected by the faul
