LZ-22 partial impedance relay usually used as measuring element on distance protection of the line at small or big current power system.
偏移特性阻抗继电器常用于小电流或大电流接地系统中作为输电线路距离保护的测量元件。
The proposed method can be used both on-line and off-line in the relay parallel setting and coordination of a large-scale power system.
该方法既适用于大电网继电保护离线并行整定计算又适用于在线并行整定计算。
When a fault occurs in power system, the relevant relay will operate and send out trip order to clear the faulted transmission line or other parts.
当电力系统发生故障时，系统中的保护装置动作，将故障线路或元件切除。
