Measuring technique of multi-standard leakage current with single human body impedance network

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 measurements is designed.This system is comprised of single body impedance network,a signal processing circuit,a high-speed data acquisition DSP system and PC.The experiment results show that the measuring method conforms to a variety of standards.
