Abstract

Progress in current measurement technology is of paramount importance in power monitoring and protection of power systems. To this aim, magnetic sensors arrays are proposed as current transducers able to meet the requirements of fast and accurate current measurement within a wide amplitude and frequency range. This paper investigates the impact of the displacement of the magnetic sensors on the accuracy of the current transducer when measuring transient currents in a three-phase rectangular conductors system. The dependence on the number of sensors is also investigated.

磁传感器阵列电流传感鲁棒性分析
电流测量技术的进步对电力系统的监测和保护至关重要。为此,提出了磁传感器阵列作为电流传感器,能够满足在宽幅度和宽频率范围内快速准确测量电流的要求。本文研究了在三相矩形导体系统中测量瞬态电流时,磁传感器位移对电流传感器精度的影响。此外,还研究了传感器数量的依赖性。
