Abstract: The present invention relates to an apparatus for identifying a leakage suspicious zone by measuring a voltage fluctuation rate between a neutral line of PEN where a leakage current is returned and a remote ground and detecting an electric leakage source along a buried path of a power line within the zone instead of the conventional current measurement method, to detect an electric leakage zone of a power line in a neutral line common ground power grid, and to a method thereof. As in the prior art, a grounded neutral line voltage is obtained from an exposed equipotential conductor or nearby customer facility without entering a power line PEN place, and a voltage difference fluctuation rate between the neutral line and the remote ground is obtained to determine a leakage suspicious zone, and a power line buried path is traced in a power line PEN having a low voltage difference fluctuation rate to measure a ground potential without the need to identify the configuration of the power line in advance to measure a vector sum current, and thus a leakage point can be recognized. Therefore, places with a low voltage fluctuation rate due to the increased ground potential in nearby customer facility of PEN designed to serve as a return point of a leakage current, or the like are defined and reduced as a leakage detection target to perform leakage detection on the ground to remove an electric leakage source. Particularly, it is possible to enable an efficient and economical leakage detection by easily identifying a leakage suspicious zone by measuring whether the ground potential rises in a large number of neutral line ungrounded customer facilities and concentrating only on power lines within the zone, since the environment is changed from a neutral line single ground to a common ground like in Korea.
