Detection of Arcing in Low Voltage Distribution Systems

Abstract

The paper proposes algorithms based on both frequency and time-frequency analysis for characterization of arcing in low voltage (230 V) distribution systems. A filter bank based approach has been suggested to identify arcing. The protection system aims at preventing fire-hazards resulting from such sustained arcing currents. Experiments have been designed to simulate contact arcing in the laboratory. The algorithms are tested on the recorded data and the time-complexity has been studied.
