The test technology of electrical safety performances based on IEC international standards

The test technology of electrical safety performance based on IEC international standards is put forward in the paper, including mainly four test parameters: leakage current, high-voltage withstand, insulation resistance and ground resistance. The definitions, the types, the testing purposes and methods of these parameters are also proposed. Based on the technology, we construct a system for data collection, processing and controlling with a PC, a high-performance microcomputer ADμC842 and a FPGA, and adopts a VI technology to develop an integrated testing system for electrical safety performance. The system can be applied to both the certification testing of products and quality control in manufacturing and provides an authenticating measure for the domestic electrical equipments to enter international markets.
