PURPOSE: A method for managing a resistive leakage current is provided to enable a manger to monitor a detected amount of a resistivity leakage current which is visually related to actual fire. CONSTITUTION: A leakage current detection unit inputs a current flowing in a wire and detects a leakage current(S10). A resistive leakage current detector detects only a resistive leakage current from the detected leakage currents and outputs the resistive leakage current to a controller(S20). The controller determines that the detected resistive leakage current belongs to which danger step from danger steps classified by a preset current value range according to dangers(S30). The controller generates and outputs display control data which is displayed through a display unit to identify the determined danger step of the resistive leakage current(S40). The display unit receives the display control data and display to identify the danger degree of the resistivity leakage current(S50). |
