摘要
对电流传感器的误差进行了分析,研制了一种用于高压电容性设备在线监测的穿心式高准确度微电流传感器。通过单片机系统,对激磁电流进行补偿,使传感器近似工作在"零磁通"状态。测试表明,补偿收到了良好的效果。
The error of the current transducer is analyzed. A type of low current transducer with cored structure and high accuracy is described which is specially designed for on line monitoring of high voltage apparatus. The circuit in the transducer can track the variation of magnetizing current and compensate it by single chip processor systems automatically to assure the magnetic core working in 'zero flux' condition. The test of the current transducer shows that the design gets satisfactory results.
