The present invention relates to an apparatus and a method for updating cable burial data and acquiring maintenance data by identifying a burial path of a cable and a rising point of ground potential at the same time. Additionally, when a survey signal current flows by being distributed into a plurality of paths by a neutral line multiple earth and a new renewable energy source link, a logic is designed to classify and determine such a signal, and methods of analyzing signal generation and signal reception are actualized for the accurate classification of the magnetic signal direction and the logic. |
