Arc Fault Discharges Indication by Deviation From Regular Processes in The Loads of Aerial Vehicles Electrical Systems

Abstract

The paper presents the results of the analysis, studies and computer simulation of the series type arc fault discharges, based on the load current deviations, abnormal for the regular processes and normalized current ripples. This method assumes continuous load current monitoring and its comparison with the reference value. There is a possibility that the information on loads state, being uploaded into processor of the Secondary Power Distribution Unit, would be enough for the aircraft electric power distribution systems with preassigned set of loads, being developed. The considered method arouses interest as the least costly. Thus, the main attention is paid to it in the framework of this paper.
