摘要
分析了现有监视线保护存在的问题，提出了通过正交变换来消除干扰信号影响的终端加电阻的交流监视线保护原理，并且通过了理论和实验验证。
The protection principles of the current monitor wire are analyzed in this paper Then the protection principle of an AC monitor wire with the terminal connected to a resistance is discussed, which can eliminate the effect of the stray current by the orthogonal transformation. Finally this principle is verified both by theory and experiments.
