Abstract

A new topology for an openable Faraday current sensor is presented with a demonstrated resolution of 7.2 mA/ radicalHz over a measurement range from 1 to 1500 A. The sensitivity of the system is 2.21 x 10(-5) rad/A. Since this sensor is fabricated in an openable form, emulating a conventional current clamp, it can be used either in permanent installations or for short-term diagnostic studies.

摘要

提出了一种用于可开启式法拉第电流传感器的新拓扑结构，在1至1500 A的测量范围内，其分辨率达到7.2 mA/√Hz。该系统的灵敏度为2.21×10⁻⁵ rad/A。由于这种传感器以可开启的形式制造，模拟传统电流钳，因此它既可以用于永久性安装，也可以用于短期诊断研究。
