ABSTRACT:
A device and a method for leakage detection and leakage location in an installation, in particular in a pipeline, include a collecting line which is permeable to a substance and is connected to a pump and to a sensor for the substance. A metal wire is disposed outside and along the collecting line and is connected to a negative pole of a direct current source. When a solution, for example salt water, emerges from a leak in a pipeline, a gas, in particular hydrogen, is obtained by electrolysis at the metal wire. A concentration maximum of the gas in the collecting line is then detected and located.
