Detection of magnetic fields (induced through power in current lines and metallic lines in the underground) with a radio detection receiver

• Passive locating
  Localization of live wires (energized current lines) and grounded wires
  Localization of radio signals which are present at almost all metallic lines in the underground


• Active locating
  Connection of a signal to the searched line

• Inductive connection
• Probe insertion at accessible parts of pipes
• . Galvanic (direct) connection with a kind of sending pincers
