Beschreibung
Zusammenfassung:	A fault monitoring system (80) for an electrical substation (83) includes one or more arrays (82) of acoustic sensors (90) placed around a substation boundary and configured to measure acoustic pressure waves. A processing circuitry (88) in the fault monitoring system (80) localizes and identifies faults in the substation (83) and includes a sound source localization module (102) to identify an area of a sound source based on the acoustic pressure waves. A beamforming module (104) of processing circuitry (88) provides enhanced acoustic pressure waves by eliminating background noise and interfering noise from the acoustic pressure waves and a component signature classification module (106) in the processing circuitry (88) compares enhanced acoustic pressure waves with component signatures to classify the acoustic pressure waves into various events to detect faults in the electrical substation (83).
