Research on Oil Pressure Rise and Fluctuation Due to Arcing Faults Inside Transformers

IEEE Transactions on Power Delivery, 2023
Oil-immersed transformer internal pressure rise and subsequent rupture due to arcing faults have received considerable attention for several decades. However, because of the difficulties, explosion risks and measurement constraints of on-site fault tests,

A Novel Arcing Detection Model of Pantograph–Catenary for High-Speed Train in Complex Scenes

IEEE Transactions on Instrumentation and Measurement, 2023
The pantograph–catenary system is crucial for transferring electrical power from catenary lines to electrified train and the occurrence of arcing could damage railway operations; thus, it is important to detect arcing.

Effect of Arcing Time on Voltage Distribution of Double-Break Vacuum Circuit Breaker During the Transient Recovery Voltage Rising Phase

IEEE Transactions on Plasma Science, 2021
Grading capacitors are required to balance the voltage distribution of the double-break vacuum circuit breaker. However, large grading capacitors increase the magnitude and duration of the reignition current.

Influence of the Crosswind on the Pantograph Arcing Dynamics

IEEE Transactions on Plasma Science, 2020
As one of the most important electrified railway components, the pantograph-catenary (PC) system plays a key role in the energy transfer for the train through the sliding electric contact.

High-Speed Arcing Fault Detection: Using the Light Spectrum

IEEE Industry Applications Magazine, 2020
Unlike short circuit faults in power systems, arcing faults produce intense light during fault events. Light-sensing technology has been under development to detect arc faults since the 1980s.

Characterization of the arcing phenomenon in micro-EDM and its effect on key mechanical properties of medical-grade Nitinol

, 2020
After reporting on the ability of micro-EDM to significantly alter the transformation behaviour of Nitinol whereby increasing discharge energy reduces thermal hysteresis and results in a three-peak reverse phase transformation on heating, this study ...
