Abstract
A mobile earth leaking survey apparatus is provided. The apparatus includes a magnetic field sensor. The apparatus includes a plurality of electrodes configured to be capacitively coupled to ground. The apparatus includes a signal timing unit for finding and setting a time T by analyzing signals input from the magnetic field sensor, wherein the time T matches a signal start time of a survey current transmitter. The apparatus includes a signal detection unit for identifying a polarity and a magnitude of a signal from the magnetic field sensor for a predetermined discrete period of time at a predetermined interval time from the time T. The apparatus includes a potential measuring unit for measuring an earth potential value input from the plurality of electrodes.
