Due to completely working under open-air conditions without backup equipment, the
overhead contact lines (OCLs) are suffering from external extreme weather conditions …

Overhead contact lines (OCLs) are electric transmission lines that power railways, which are
constantly threatened by external weather and environmental factors due to their outdoor …

The traction power supply system (TPSS) is the only source of power for electric
locomotives. The huge power fluctuations and complex operating conditions of the TPSS …

Extreme weather events pose significant risks to power systems, necessitating effective risk
forewarning and management strategies. A few existing researches have concerned the …

In high-speed railway (HSR), directly reclosing a circuit breaker after a fault trip can result in
a large second overcurrent, causing insulation degradation, equipment damage, and even …

The geological complexity, environmental sensitivity, and ecological fragility inherent in
complex and difficult areas (CDAs) present new opportunities and challenges for …

A variety of Chinese textual operational text data has been recorded during the operation
and maintenance of the high-speed railway catenary system. Such defect text records can …

The sectional insulator with arcing horns is indispensable for electrified railways' overhead
contact system (OCS). When these arcing horns are damaged, broken, or detached, arcing …

To ensure the high-reliability operation of overhead contact lines (OCLs), this paper
proposes a data-driven time dependent reliability prediction approach, incorporating the …

Aiming at the problem that the existing relay protection of traction power supply system mis-
operates when an out-of-phase fault occurs, based on the sum of two phase impedance, a …
