Paper Abstract

The working principle, design and implementation are described for a new design of leakage current test system, which is composed of human body's impedance network, detector switch circuit, the circuit including MCU and CPLD for control and measurement, can achieve peak detection, true RMS detection, real-time display of waveform. According to many international testing standards such as IEC, UL, GB, the system has a broader measuring scope of frequency and higher accuracy with good human-computer interface and calibration function.
