IET Electrical Systems in Transportation, Volume 2023, Issue 1, 2023., 2023 Droppers and jumpers are important components of railway overhead line electrification. Their effective maintenance is critical for the railway’s safe and reliable operation; the consequences of their failure can be disproportionally serious. This paper systematically analyses the components’ failure by applying the method of failure modes and effects ...

Research on time–frequency characteristics of contact force based on wavelet transform
IET Electrical Systems in Transportation, Volume 12, Issue 4, Page 287-297, December 2022., 2022 Abstract When a train runs at high speed, affected by the structural characteristics of the catenary, the contact force changes periodically with span and dropper spacing. However, as the running speed of the train increases, the periodic signal of the contact force changes owing to the fluctuation of the catenary and the vibration of the pantograph ...

The Journal of Engineering, Volume 2022, Issue 11, Page 1076-1085, November 2022., 2022 Abstract Vibration compensation in track displacement monitoring is explored by using rail image feature points. The key point is to compare the image of the rail to be tested with the image of the standard rail. A downstream section of Metro Line A is selected for real time analysis of image.

Study on electric spark discharge between pantograph and catenary in electrified railway
IET Electrical Systems in Transportation, Volume 12, Issue 2, Page 128-142, June 2022., 2022 Abstract The electric spark caused by pantograph‐catenary (PC) electrical contact failure happens frequently, it is a kind of arcing phenomenon which can severely affect the current collection of PC. The theoretical analysis and modelling of PC electric spark are tried.

Voltage transient management for Alternating Current trains with vacuum circuit breakers
IET Electrical Systems in Transportation, Volume 12, Issue 1, Page 1-14, March 2022., 2022 Abstract Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7 Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase medium‐voltage distribution system. Switching inductive loads with a vacuum circuit breaker (VCB) in MV traction systems poses familiar challenges as well as ...
