Research on testing technique of leakage current corresponding to IEC 61010

QIU Ming-xiao,LIU Gui-li,LI Dong,WANG Xiao-fei (Department of Electronic Information Engineeing, Beijing Institute of Machinery, Beijing 100085 ,China)  
A leakage current testing system controlled by IPC according to the standard of IEC 61010 is introduced for the implementation of the electric safety standard. The weighted measuring network of simulating body-resistance is adopted in this system. The system consists of an isolated transformer, a measuring network, a signal processing circuit, an isolated and amplifying circuit, an interface circuit, a high-speed A/D data acquisition card and an IPC. The experiment indicates that this system is steady and the precision is kept within one percent.
