纵联保护

目前，我国高压输电线路基本上都配备双套主保护，一般采用纵联保护原理。

High voltage transmission lines in China are equipped with double sets of main protection , generally pilot protection principle .

纵联保护在原理上比较完备，理论上具有绝对的选择性，故障判断和隔离所需的时间较短，在实际应用中动作的准确率也较高，可较好满足高压系统对继电保护的要求。

Pilot protection is perfect in principle and has absolute selectivity in theory , needs less time for fault detection and isolation and has higher rate of correct action , it can meet the protective requirements of high-voltage system well .
