چکیده
Electric arcing due to contact interruption between the pantograph and overhead line in electrified railway networks is an important unwanted phenomenon. Arcing events are short-term power quality disturbances that produce significant electromagnetic both conducted radiated as well increased degradation on wire strip of pantograph. Early-stage detection can prevent further deterioration current collection quality, reduce excessive wear pantograph-catenary system, mitigate failure strip. This paper presents a novel arc method for DC networks. The quantifies rate-of-change instantaneous phase oscillating signal during occurrence through Hilbert transform. Application practical data measurements, demonstrates derivative useful parameter detecting localizing electric arcs coasting regenerative braking phases running locomotive. detected number may be used calculate distribution per kilometre alternative estimation index consequently assess system performance. also contribute lowering predictive maintenance costs inspections works these performed only at determined sections extracted by using time locations speed profiles

متن کاملA Novel Ground Fault Identification Method for 2 × 5 kV Railway Power Supply Systems
The location of ground faults in railway electric lines in 2 × 5 kV railway power supply systems is a difficult task. In both 1 × 25 kV and transmission power systems it is common practice to use distance protection relays to clear ground faults and localize their positions. However, in the particular case of this 2 × 25 kV system, due to the widespread use of autotransformers, the relation bet...
