摘　　要：介绍了一种采用单一人体阻抗网络实现符合多标准的泄漏电流测试技术。首先对多标准中提出的测量泄漏电流过程中所采用的多种人体阻抗网络进行分析,进而得出频率因数。在此基础上对测得值进行加权计算实现多标准的泄漏电流测试系统。该系统由单一模拟人体阻抗网络、信号调理电路、DSP高速数据采集系统和计算机等组成。实验表明,测试方法符合多种标准的测试要求。The measuring technique of multi-standard leakage current with single human body impedance network is introduced. Various simulation human body impedance networks, which developed in different standards in the test procedure of leakage current, have been analyzed to obtain frequency factor. A system corresponding to multi-standard which based on weighted value of measure- ments is designed. This system is comprised of single body impedance network, a signal processing circuit, a high-speed data ac- quisition DSP system and PC. The experiment results show that the measuring method conforms to a variety of standards.
