摘要

为了保证电力系统的正确运行，需要进行电流测量。传统的电流互感器仍广泛应用于此类电网，但其众所周知的局限性使其不适合传入的智能电表。本文提出了一种基于对一次电流产生的磁场进行适当测量的电流传感器。它的主要特点是特殊的几何结构，可以忽略外场的影响，而不使用传统的线圈结构。

A self-shielded current transducer for power system application

Current measurement is required to ensure the correct operation of power systems. Conventional current transformers are still widly employed in such networks but their well-known limits make them not suitable for the incoming smart meters. In this paper, a current transducer based on proper measurements of the magnetic field produced by the primary current is proposed. Its main feature is the particular geometry that allows neglecting the effect of external fields without using traditional coil-structure.
