Title:
APPARATUS AND METHOD FOR DETECTING BURIED POWER LINE PATH BY USING HIGH-FREQUENCY LOW-POWER SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/058644
Kind Code:
A1
Abstract:
The present application relates to an apparatus and method for detecting a buried power line path, the apparatus comprising: a transmitter that, when transmitting a current pulse signal to a conductor (power line) of a common distribution network, outputs an output obtained by selecting a balanced/unbalanced voltage, receiving an input of the selected balanced/unbalanced voltage, and then rectifying same, as a current pulse in the form of a pulse without modulation or a frequency modulation signal; and a receiver that obtains a difference value in each direction by inductively coupling the pulse or frequency modulation signal with a plurality of magnetic field sensors at a near magnetic field distance, to thereby obtain a depth.
