摘要

With the more and more widespread use of power electronic equipment, there will be more and more current signals with 0.1%~200%In (rated current of 200A) and frequency bandwidth of 0~21th harmonics. In order to ensure accurate current For signal transmission and electric energy measurement, current transformer technology research and device development with a current range of 0.1%~200%In (rated current of 200A) and a frequency width of 0-21 harmonics are required. This paper conducts experimental research and analysis on the measurement error of a self-developed wide-frequency and wide-range current transformer, and analyzes the error under the action of wide-frequency and wide-range current from the two aspects of amplitude error ratio and angle error. The main conclusions are as follows: Under the action of broadband current, the amplitude error ratio and angle error of the current transformer gradually decrease with the increase of frequency; the angle error of the current transformer also gradually decreases with the increase of frequency. Under the action of 0.1% to 200% rated current, the amplitude error ratio of the current transformer is mainly concentrated in -0.02 to -0.03. The angle error of the current transformer only needs to be concentrated in 0.4°-1.2°.
