Beschreibung
Zusammenfassung:	Method (1) for identifying the source of pressure transients in a water distribution network comprising a plurality of high-frequency pressure sensors installed therein, said method comprising : - An acquisition step (10) to acquire a plurality of pressures values for each high frequency pressure sensor during a preset time limit, said plurality of pressures values defining a sampled pressure variation record nearby each sensor during said preset time limit; - A detection step (11) for detecting transient events amongst the sampled pressure variation record; - A grouping step (12) for grouping detected transient events amongst the sampled pressure variation record; and - A localization step (13) for localizing the source of said grouped transient events in function of said sampled pressure variation records.
