英文摘要：

This paper carried out many simulation tests for different positions and different types of fault. These tests were based on the frequency spectrum analysis of high-frequency signal and faulty signal. Meanwhile, research on rite reliability of transient-based protection under the interferer of high frequency signal was performed.
