摘要
Abstract
In order to monitor discharging process of the pulsed high magnetic facility,the discharge current must be measured accurately.In this paper,the two stages of discharge and the characteristics of the discharge current are analyzed in details by simulation.According to the characteristics of the discharge current and the fundamental principle of air-core coil,a measurement scenario of combination printed circuit board(PCB) air-core coil and digital integrator based on improved Al-Alaoui algorithm is put forward.A calibration system using Pearson 4427 current transformer is designed and tested.These tests verify the accuracy and the stability of the scenario can meet the measurement requirement of pulsed high current.关键词
