• 检漏继电器采用零序电抗器并不影响选择性漏电保护的实现,而对其可靠工作作用明显;

    A feeding switch with a leakage protection function to replace a leakage check relay should not be adopted for practices.

  • 采用具有选择性电流方向继电器这种相互分隔直流系统保护相对简单

    Protection for these isolated systems has been a relatively simple task, which is carried out using over current directional relays with selectivity.

  • 选择性继电器诸如系统瞬间切换负载突变之类的无害异常情况作反应

    Selectivity: The relay must not respond to abnormal, but harmless, system conditions such as switching transients or sudden changes in load.

  • 重要根据故障特征继电器参数,既保证区外故障时的选择性在区内故障时获得足够灵敏度

    It is important to set the parameters of the relay according to the fault characteristics. Thus the relay will get selectivity and sensitivity.
