harmonic measure method is the key of the measurement. in this paper, the harmonic measure method which based on the multiple frequency rotate transform theory is researched and analyzed.
谐波测量方法是谐波测量的核心环节,本文对基于倍频旋转变换理论的谐波测量方法进行了研究分析。
the system can measure the harmonic in hv power network, and avoid the problem of harmonic measure signal distortion caused by capacity type voltage transformer (cvt).
