摘　　要：在电力系统的继电保护中,保护装置的算法来源于基本的电力系统分析及短路故障计算,并且装置对电压电流的方向是有一定的要求,特别是新设备在投运过程中,怎么判断装置的电压电流接线的正确性尤为重要。因此,本文介绍了常规主变及线路的带负荷检查方法并对其进行分析。In the power system relay protection, protection device algorithm was come from the basic power system analysis and short circuit fault calculation. The device had certain requirements about the direction of voltage and current, especially during the operation of new equipment, how to judge the correctness of the voltage and current wiring of the device was very important. The paper introduced and analyzed the on -load test method of main transformer and line.

关 键 词：极性 带负荷检查 线路保护 主变保护.
