“…In recent decades, the EMD from OLPC are usually investigated in three aspects: 1) Measurement of EMD from OLPC. As far as the measurement of electrical characteristics of EMD from OLPC, both measurement on-site and in laboratory are studied [6][7][8][9] . Indeed, the literatures mentioned above care about the characteristics of arcing, radiated characteristics and the hazards of the sensitive equipment brought by EMD.…”

“…They performed their work in a laboratory simulation environment and made an arc detection process; however, they did not address the wear in the current collection strips. The newest method of measuring radiation due to pantograph contact with the catenary on high-speed trains was developed by Ma et al [24]. Song et al [25] carried out a study that took into account the contact surface and the dynamic performance of pantograph catenary systems.…”

In pantographs, current collector strips transmit the electrical energy they receive from the catenary to the locomotive and provide the necessary power for the locomotive's movement. In order for the current collector strips to transmit electricity to the locomotive in a healthy way, their surface must be smooth. Wear on the surface of the current collector strips reduces conductivity and can create arcs, endangering the health and safety of the pantograph and catenary system. In this paper, a Convolutional Neural Network (CNN) architecture is developed to detect wear on the current collector strips. Images obtained from pantographs used on railways were created with a clean and improved data set using Hough Transform and Power Law Transform. The created dataset contains 909 pantograph images. This dataset was trained and tested with both the developed CNN architecture and classic deep learning architectures (ResNet50, VGG16). The experimental results show that the developed CNN architecture's training results and test results are more successful than classical architectures.

“…Another resistive arc model is proposed for investigating the interaction between the arc and the remaining part of the electronic circuit [10]. The arcing implies a large transient and the damage to the contact point [11][12][13]. The waveform of the pantograph arcing looks like high-frequency pulse width modulation and such a transient process could last for a fraction of a second [14].…”

The pantograph arcing phenomenon may shorten the service life of a pantograph and even destroy onboard devices and instruments, due to the irregular motions of the train and the intermittent line–pantograph disconnection. This paper points out that abrupt inductive energy from the magnetizing inductance of the traction transformer can lead to an electromagnetic transient process with unexpected overvoltage across it. Further, a supercapacitor-based power electronic system is proposed, which can not only redirect the inductive energy to the supercapacitor pack through bidirectional converters but also mitigate the overvoltage across the main electrical equipment when pantograph arcing occurs. Simulation results show the overvoltage could be reduced and the energy stored in the supercapacitor which could also be used to provide energy for sensors or other devices.
