摘　　要：通过使用基于无线传输相位差比较方法和强抗千倍干扰选频测量技术,能在千倍工频干扰下对杆塔的分流向量进行准确的测量,能准确有效剔除接地测量过程中分流成分,提高接地网接地阻抗测量的准确度,为保证电力系统在雷击或短路故障下的安全运行和人员的安全具有重要的意义。In this paper,by using different frequency measurement,phase comparison method based on wireless transmission,Rogowski coil shunt signal sampling and high-precision,high-resolution,anti-interference of the Rogowski coil wireless measuring devices can thousand fold lower frequency interference the diversion of tower vector accurate measurements,which can accurately and effectively weed out the diversion of ingredients to improve accuracy. This method has significance for ensuring the safe operation of power system and workers＇ safety.
