relay operated meaning in English

继电器操纵的
继电器的

If only one phase - to - ground relay operates , the operated phase is tripped in a single - pole tripping scheme ; otherwise , the tree phase of the protected line is tripped
提出了继电器按单相设置保护方案， ?相继电器动作跳单相，超过两相继电器动作认为是相间故障则三相跳闸。
The operation characteristic of the new relay is analyzed in theory and verified by the simulation tests . the new relay operates with clear selectivity and high operation speed and can satisfy the demand of the protection for the ehv transmission line . the performance of the fault component impedance relay has been improved and the misoperaion of the healthy phase under cross - country fault and close - in fault have been avoided
理论分析及仿真计算表明，基于自适应补偿的突变量距离继电器有很好的选择性和速动性，完全能够满足高压线路保护的需要，显著提高了突变量距离的性能，解决了其在大电源出口单相故障以及正反向复故障可能会误跳三相的缺点。
