| Abstract: | The accuracy of DC high current measuring equipments has an important influence on the quality of products,energy consumption control and so on.Because there are some difficulties in caribrating DC high current measuring equipments,this paper proposes to use the superconducting equal ampere-turns coil instead of the traditional equal ampere-turns coil to make the caribration system.The system will be used to calibrate flexible DC current sensors for measuring high current,and this technology can reduce the technical index requirements of the standard DC current source in the system. |
