Abstract
A non-electric shock protection system and method thereof for preventing an electric shock caused by shielding, absorption, and reduction of a leakage current, and preventing an arc by blocking an external surge. The system includes a multi-functional ground fault portion for leakage current shielding and ground distribution, a noise filter portion for shielding, absorbing and reducing a leakage current at a power terminal L and a neutral line terminal N, a power portion for supplying a power, a main control portion for controlling each portion of the system to output a normal power and control an amount of a leakage current, an abnormal current sensing portion for collecting the abnormal leakage currents and noise current, a pulse width modulation control portion for receiving a power from the abnormal current sensing portion and compensating the power through the amplitude and frequency modulation and a polarity indicating portion
