摘要

The present invention relates to a detection device of a leakage current for deterioration diagnosis of DC lightning arresters. The detection device of a leakage current for deterioration diagnosis of DC lightning arresters according to one embodiment of the present invention includes: a ground part (10); a measurement line (20); a measurement impedance (30); a microprocessor (40:MPU); power source part (50); and a case (60). According to one embodiment of the present invention, one end of the measurement line is connected to the upper ground terminal (11) of the ground part (10). The other end of the measurement line is connected to the lower ground terminal (12). More particularly, in an aspect of the present invention, the detection device of a leakage current for deterioration diagnosis of DC lightning arresters can include other embodiments.
