| Abstract: | The application of line fault location based on traveling wave greatly improves the accuracy of line fault location, and makes it convenient to search fauh and make urgent repairs. However, some problems still exist in the application of line fault location based on traveling wave,and location error and non-valid report frequently occur. This paper analyses the causes of the existing problems,and puts forward some solutions. |
