Due to the extensive use of power electronic devices and nonlinear loads, the resulting of distortion in power grid voltage and current waveform becomes more and more serious. There not only exist integer harmonics of larger containing rate, but also include non integer harmonics of abundant spectral components, what is called inter-harmonic. Through the experiment platform having built before, this paper measures the frequency characteristics of current transformer in the 10Hz-2.5kHz, at the same time, the frequency characteristics of current transformer is analyzed theoretically from the point of the transfer function. The actual measurement could proof mutually well with theory, and the study found that, in inter-harmonic wave and high harmonics, the error of current transformer are more serious than in frequency. In addition, by collecting data actually, and we found that the error of fundamental wave brought by current transformer and the error of harmonic power increased obviously when they were compared with the error of current transformer itself, besides, harmonic power error was affected more.
