Claims
- 1. A device for leakage detection and leakage location in an installation, comprising:
- a collecting line permeable to a substance;
- a pump connected to said collecting line;
- a sensor connected to said collecting line for sensing the substance;
- a metal wire disposed outside and along said collecting line; and
- a direct current source having a negative pole connected to said metal wire.
- 2. The device according to claim 1, wherein said collecting line is disposed in the vicinity of a pipeline of the installation.
- 3. The device according to claim 1, including a collecting channel disposed underneath said collecting line and said metal wire.
- 4. The device according to claim 1, including an absorbent material surrounding said collecting line and said metal wire.
- 5. The device according to claim 4, wherein said collecting line and said metal wire are disposed together along a pipeline of the installation between an 8 o'clock and a 9 o'clock position.
- 6. The device according to claim 4, wherein said collecting line and said metal wire are disposed together along a pipeline of the installation between a 3 o'clock and a 4 o'clock position.
- 7. The device according to claim 1, wherein said collecting line and said metal wire are disposed underneath a pipeline of the installation.
- 8. The device according to claim 1, wherein said direct current source is variable.
- 9. The device according to claim 1, including a metal electrode to be disposed in the ground, said direct current source having a positive pole connected to said metal electrode.
- 10. The device according to claim 1, including a further metal wire disposed outside and along said collecting line at a distance from said metal wire connected to the negative pole of said direct current source, said direct current source having a positive pole connected to said further metal wire.
- 11. The device according to claim 10, wherein said metal wires are formed of different metals.
- 12. The device according to claim 11, wherein one of said metal wires is formed of copper and the other of said metal wires is formed of zinc-plated copper.
- 13. The device according to claim 10, including an ammeter incorporated into at least one of said metal wires.
- 14. The device according to claim 10, wherein each of said two metal wires have a first and a second end and said direct current source associated with an ammeter is connectable to said first or second ends of said metal wires in turn.
- 15. A method for leakage detection and leakage location in an installation, which comprises:
- obtaining a gas by electrolysis from a solution having emerged from a leak; and
- detecting and locating a concentration maximum of the gas having penetrated into a permeable collecting line.
- 16. The method according to claim 15, which comprises carrying out the obtaining step by electrolysis from a solution having emerged from a leak in a pipeline of the installation.
