| 介绍了1种新的架空线路故障测距方法。该方法只测量线路的电流，测量精度不受短路过程电阻的影响。根据该方法研制成以80C196单片机系统为主的架空线故障测距装置。经电力系统模拟试验：该装置对点能准确定位，测量误差在3%以内，具有较高的工程实用价值。 |

| Abstract: |
| A new fault location method for power transmission line is proposes,by which only the line reactance is to be measured and the fault interim resistance will not effect the measuring precision. A fault locator for power transmission line using 80C196MCU system as its core is developed based on the method. The simulation test shows that the fault location can be correctly pointed out, and the measuring error is within 3%. Therefore, it has a higher practical value in engineering. |
