Abstract (en)
A method (100) and system (200) for localizing defective parts of a power system (10) suitable for supplying railway vehicles, which power system (10) comprises a main power-carrying conductor (11) and an associated current collector equipment (12). The actual position (P) of a vehicle (2) travelling along a railway line is tracked and values (V<sub>I,V</sub>) related to a first parameter (I, V) indicative of an actual operative status of the main power-carrying conductor (11) and values (V<sub>F</sub>) related to a second parameter (F) indicative of an actual operative status of the current collector equipment (12) are first calculated and then compared with a first predefined threshold (Th<sub>i,v</sub>) and with a second predefined threshold (T<sub>F</sub>), respectively, during a first predetermined interval of time (T<sub>1</sub>) and a following second predetermined interval of time (T<sub>2</sub>). Depending on the results of the comparison, the method and system are able to localize and discriminate if a defective part is present on the power-carrying conductor (11) or on the current collector equipment (12) and to generate a corresponding alarm signal for maintenance.
