摘要

本文介绍了测量电流传感器(MCT)磁场和电场图像的建模方法。我们认为任何不直接连接到测量电流，但位于距离导体一定距离的传感器都是MCT。因此，这种MCT不需要增加类绝缘。本文研究了在主电流和输出信号中产生附加噪声的电流的影响下，MCT磁流中的磁场分布。给出了二次MCT信号获取的数学模型。最后得出了采用小型换能器进行继电保护和自动化的可能性。

Modeling of A Small-Sized Distance Current Transducer

This paper presents modeling of the picture of magnetic and electric fields of a measuring current transducer (MCT). We consider any transducer that is not connected directly to the measured current, but is located at a distance from the conductor, as an MCT. Due to this, such an MCT does not require an increased class insulation. The paper investigates the distribution of the magnetic field in the MCT magnetic current under the influence of the main current and the current that causes additional noise in the output signal. The mathematical model for obtaining the secondary MCT signal is described as well. The conclusion is drawn about the possibility of using a small-sized transducer for relay protection and automation.
