Zusammenfassung:	An apparatus (9) for detecting an electrical arc fault in an electrical system (1), is disclosed. The apparatus comprises an interface (13) configured for receiving data on operation of the electrical system and a processing unit (15) configured to: perform a time-domain analysis of the data; if at least one time-domain parameter of the data meets a potential arc fault condition, enabling the detection of an arc fault event based on a frequency-domain analysis of the data.
