摘要
Disclosed are a method for detecting resistive leakage current of a nonlinear element arrester using a differential method and an apparatus therefor. The method for detecting the resistive leakage current of the nonlinear element arrester according to one embodiment of the present invention may comprise the steps of: calculating a differential voltage by differentiating an operating voltage inputted into the arrester with respect to time; detecting capacitance of the arrester on the basis of total leakage current applied through the arrester and the differential voltage; calculating capacitive leakage current of the arrester using the capacitance; and detecting the resistive leakage current of the arrester through the difference between the total leakage current and the capacitive leakage current.
