Dataset of measured and commented pantograph electric arcs in DC railways [PDF]

Data in Brief, 2020
DC railways are characterized by particularly intense arcing caused by pantograph detachment, due to the large current intensity and the general implementation of onboard resonant filters, whose transient response is triggered by electric transients ...

How pantograph electric arcs affect energy efficiency in DC railway vehicles [PDF]

2020 IEEE Vehicle Power and Propulsion Conference (VPPC), 2020
In DC electrified railways pantograph electric arcs represent not only a disturbance, but the step change of the pantograph voltage affects power losses directly and indirectly. The available line voltage is reduced if the train is in traction condition,

Pantograph Arc’s Energy Characters Under Various Load

机车电传动, 2011
Due to the increasing speed of the locomotive, the pantograph-catenary disconnection was getting worse, and the pantograph arc occured frequently. The pantograph arc etched the pantograph slider and contact wire, and the etching level was influenced by ...

Pantograph-To-OHL Arc: Conducted Effects in DC Railway Supply System [PDF]

IEEE Transactions on Instrumentation and Measurement, 2018
The electrical arc occurring in the sliding contact between the supply contact line and the current collector (pantograph) of an electrical locomotive is a fast transient phenomenon able to degrade progressively the line-To-pantograph contact quality and,

Characteristic analysis of pantograph–catenary detachment arc based on double‐pantograph–catenary dynamics in electrified railways

IET Electrical Systems in Transportation, 2022
With the increase of train speed in electrified railways, the increasingly violent interaction of pantograph–catenary (PC) makes the PC detachment arc an extrusive phenomenon, especially in the double‐pantograph–catenary (DPC) system.

Electrical Characteristics of Pantograph Arcs in DC Railways: Infrastructure Influence [PDF]

, 2019
Electric arcs are an unavoidable by-product of current collection by sliding contact in electrified transportation systems. Electric arcs are transient phenomena with implications for PQ measurements and wearing estimation and prevention of the sliding ...

Study on the Ablation of Slide Plate by Pantograph–Catenary Arc Based on Pantograph Slide Material

Infrastructures
The ablation of pantograph sliders caused by pantograph–catenary arcing is a critical issue in the operation of pantograph–catenary systems. The arc discharge induces localized high temperatures that lead to the melting and even evaporation of the slider

Pantograph arc location estimation using resonant frequencies in DC railway power systems [PDF]

IEEE Transactions on Transportation Electrification, 2021
Pantograph arcing in electrified railway systems not only reduces the power collection quality of a locomotive but can also damage pantograph strips and overhead lines (OHLs).

Simulation on Operating Overvoltage of Dropping Pantograph Based on Pantograph–Catenary Arc and Variable Capacitance Model

Applied Sciences
When the electric locomotive pantograph is dropping, the interruption of pantograph catenary contact causes electromagnetic oscillation and arcing. The frequent arc burning that occurs due to charge accumulation results in the amplitude of overvoltage ...

Multiresolution Models of DC Traction Power Supply Systems With Reversible Substations [PDF]

IET Electrical Systems in Transportation
Reversible substations (RSs) permitting bidirectional power flows can recover the regenerative braking energy of trains in DC traction power supply systems (TPSSs), increasing the energy efficiency of railway systems.
