The State-of-the-Art Methods for Digital Detection and Identification of Arcing Current Faults

IEEE transactions on industry applications, 2019
This paper reviews approaches used to detect and identify arcing currents, including arcing current faults. The reviewed approaches are categorized as the time-domain, frequency-domain, and time–frequency approaches.

ARC

Proceedings of the 30th International Symposium on High-Performance Parallel and Distributed Computing, 2021
Progress in high-performance computing (HPC) systems has led to complex applications that stress the I/O subsystem by creating vast amounts of data. Lossy compression reduces data size considerably, but a single error renders lossy compressed data unusable.

Pantograph–Catenary Arcing Detection Based on Electromagnetic Radiation

IEEE transactions on electromagnetic compatibility (Print), 2019
Currently, the detection equipment for offline arcing on high-speed trains is of great interest because it can evacuate the contact state between the contact wire and the strip.

Detecting Arcing Current Faults in Medium-to-Low Voltage Transformers

IEEE/IAS Industrial and Commercial Power Systems Technical Conference
Arcing current faults occurring in a medium-to-low voltage (MV-LV) transformer can pose a challenge for transformer protection. Such faults trigger currents with lower magnitudes than those triggered by conventional faults, thus making it difficult for ...

Immersion photoacoustic spectrometer (iPAS) for arcing fault detection in power transformers.

Optics Letters, 2019
We report on the development of the first immersion photoacoustic spectrometer (iPAS) for arcing fault detection in power transformers. The spectrometer consists of a detection system and an all-optical photoacoustic sensing head mounted inside a small ...

CNN-Transformer Bridge Mode for Detecting Arcing Horn Defects in Railway Sectional Insulator

IEEE Transactions on Instrumentation and Measurement
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 can occur due to unstable contact between the pantograph and the catenary,

A Novel Arcing Power-Based Algorithm for Condition Monitoring of Electrical Wear of Circuit Breaker Contacts

IEEE Transactions on Power Delivery, 2019
This paper introduces a condition monitoring (CM) algorithm based on the circuit breaker (CB) arcing power and its related energy to estimate the electrical wear of arcing contacts. There is an electric arc occurring between the CB arcing contacts mainly

Arc structure, arc motion and gas pressure between laterally enclosed arc runners

Electrical Contacts - 1998. Proceedings of the Forty-Fourth IEEE Holm Conference on Electrical Contacts (Cat. No.98CB36238), 2001
Arc motion along parallel arc runners tightly enclosed by lateral walls was investigated experimentally, both with and without an exhaust barrier at the outlet. High speed movies (33000 frames/s) were taken and the gas pressure was measured at several locations along the path of arc motion.
