Design of Large Current Intellectual Measuring Meter

LI Zhi-yong1,XU Na1,SHI Chong-yang2(1.Xinglong Branch of Chengde Power Supply,Chengde 067000,Hebei,China;2.Department of Electrical and Electronic Engineering,Chengde Petroleum College,Chengde 067000,Hebei,China)  
A design scheme is introduced which takes magnetometer as sensor and matches with intellectual circuit.Also this paper states the electrical magnetic principle of this scheme and gives out intellectual measuring circuit.In the meantime,the reason causing measuring error is analyzed and the correspondent solution is offered.The alternating meter adapting this design can measure current over one thousand amperes.
