As an important electrical safety protection device in low voltage distribution system, residual current protection device is to protect the insulation line leakage fault; the electric shock of the people plays an important role in fault. From the protection characteristics of residual current protective device to points, those can be divided into, residual current protection device for residual pulsating direct current and residual dc, according to the residual sinusoidal alternating current.

This paper introduces a monitoring system for electric leakage protection based on AVR Single-Chip Computer, which the terminal monitoring PC communicates with AVR single-chip computer through wireless channel, so as to monitor the operational status of the residual current protective device (RCD) in real time. In addition, taking both amplitude and phase angle of the residual current as leakage protection judgment parameters could increase the accuracy of RCD effectively.
