②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.
该保护继电器实时监控电流信号，具有3段电流保护和接地漏电保护等动作特性。
The protection relay monitors the signals of currents real time and has performance characteristics of three-sect current protection, grounding leakage protection and other protections.
