利用暂态行波测距的研究

文章阐述了利用单端量暂态行波实现架空线路故障测距的原理与技术，并在此基础上推出研制的新型故障测距装置。理论分析和装置试验结果表明，在此提出了用于Ａ型行波测距技术是可行和有效的，以行波法测距为主，以阻抗法为辅并廉作启动元件可进一步提高装置的可靠性。

STUDY OF FAULT LOCATION BASED ON TRAVELLING WAVES

The theory and relevant techniques of type A fault locator based on travelling waves for high voltage overhead lines were discribed in the paper. Theoretical analyses and test results show that the techniques proposed are feasible and effective. The reliability of fault location can be improved further by combining the travedlling wave method with the impedance one.
