Zusammenfassung:	On august 31, 2014, a generalized power outage impaired the Tunisian power system. This event was particular in the time frame of the cascaded failures, where weak cross-border grid interconnection stood out as a determinant factor. North African interconnections did not support the Tunisian system during emergency. This paper presents a diagnostic review of the event based on an analysis of the precondition operational profile of the system. The chronological sequence of the blackout events are detailed and supported by real operator recording. North African power exchange assets are reviewed in view of the event. Hidden failure of protection system apparatus was particularly a triggering factor. The post-fault analysis revealed system isolation risks, corrective controller limitations. Countermeasures are proposed to enhance the system power supply reliability.
