| Abstract: | According to the theory of zero elementary wave magnetic flux current transformer, a principle of computer-regulating magnetometive force compensation zero elementary wave magnetic flux current transformer is given which has the characteristics of fast and accuracy. A principle of measuring harmonics directly according to the harmonic magnetic flux in the main core of the current transformer is proposed. It is effective to improve measurement accuracy of harmonics in power system. |
